If you look at your internet traffic with full spectrum rf, you'll most likely see that outside the data stream there's a second side stream, that is sending all of your DNS requests somewhere. If not you're ISP, then whom?
Today while browsing I come across your link it's amazing. It would be wonderful if you can provide some classes on networking as I work for Network company
I have just subscribed after watching one video. You have a knack for delivering video content while faceless. Your way of explanation is awesomely on another level. One can easily comprehend the concepts and the flow of information fully. Keep it up.
Hey your effort towards providing the quality content is just amazing!! I just wanted to say you that please make a complete detailed video on the OSI and TCP/IP MODEL. That would be really helpful 😌
I could completely relate to the remote work part, as my IT Director is adamant about everyone using a VPN, as 95% of our workforce at my employer are fully remote.
I love this channel, your content is great, I've been following you a few years now and when I need to refresh/learn something this is the first place I try to go
Thank God i found this channel! Thank you so much PCAV! You explain things so well and the animations help the information stick to my brain. I've learned so much from your videos with your "explain it like im 5" animations more than other sources! You should sign up as a Udemy teacher! I'd definitely pay top price for your class!!
I really like this channel because it has the ability to explain sometimes difficult concepts in easy and fast way. However sometimes faster isn't always better and it does leave a lot of room for deception and dishonesty about product that people don't actually need (like in this case) ...
A note about traffic logging: as of this writing, to the best of my knowledge, VPN providers aren't required, in some areas, to log traffic data. With NordVPN in particular, they will comply with law enforcement requests after putting law enforcement through the ringer, but the only records they would have would be payment data and email addresses. Still, that's something. Obviously, a discussion on completely anonymizing and privatizing one's Internet activities falls outside the scope of this video (encrypted DNS, Tor, and how those might even have their vulnerabilities), but kudos on yet again another simple, straight forward explanation on what a thing is, how it works, what it does, etc.
5 eyes, 7 eyes, 14 eyes. VPNs must comply with a legally acquired court order. Of course, some VPNs use RAM storage (not Nord). Switch off the server and the data is lost forever. The danger with TOR is you never know who is in control of the exit node, hackers, law enforcement... Safest but slowest is TOR over VPN.
@@ianl1052 "VPNs must comply..." I didn't state otherwise. "Some VPNs use RAM storage...." Interesting! "The danger with TOR...." Yep!

Great video, as always. I think you could have mentioned some downsides of VPNs. For example: VPNs can slow your internet speed. Some sites might not accept VPN connections. Some VPNs will disconnect, and reconnect; even if this is done momentarily, it can be long enough to gather data about you.
My school use your video like documentary and teach student like us. Thank you for your hard work ! Because OMG !!! my teacher explain things so bad to the point where I have to watch your video to understand what he say xD
You have done it again sir, straight to the point and very concise. Your content is awesome. Thank you! One question though, let's say you pay for a VPN here in America right and let's say you visit a country overseas would you be able to connect to the same VPN server in America or it has to be something closer to where you are located?
Even though the connection is secure between you and a specific server with a VPN, if you connect to a bad server (such as fake websites, scam downloads and so on), it no longer protects you. A VPN secures the connection, but it doesn't protect you from the server your are connecting with.
@@PowerCertAnimatedVideos I was going to ask this anyways, but what about a VPN offered by your protection software?

And two other questions: 1) If your IP address is changed, won't that cause a problem with previously saved/bookmarked websites? Wouldn't you have to reconnect/re-subscribe to each of them? 2) I can see it being useful on your laptop or cell phone, but would it be absolutely necessary on your desktop?
Some online sites (streaming, banking, etc) have blacklisted known VPN server addresses so your connection may bug out. Always best to give a VPN service a good work out during the trial period. All you have done is swapped out your current ISP tracking for a VPN further down the road.
I would like to see a more indepth videos from you. If you use a VPN you still need to go through your ISP, you are not avoiding them. Only thing is your connection is encrypted and even that, which parts are encrypted. I suppose destination of the packet must not be encrypted. Also are packets encrypted only between you and a VPN server but I guess it is not encrypted between VPN and whichever site you are trying to access?
Can you please explain in more detail how tunneling works? Is it the data just encrypted? And also, how does a VPN protect you from fake AP since you are connected to it directly?
I have a subscription with STC for internet service, but my home does not have an landline extension, so STC has partnered with Mobily to provide the connection. As such, I was provided two devices: one from Mobily (that is connected to a fiber optic cable) and a router from STC. Is there any way that I can activate the Mobily device and do away with requiring the second STC router ?
Thank for your explanation. I have a question,Do the packets go directly to the VPN server or they go first to the ISP server and then routed to the VPN server?
They have to go through your ISP first. There's no other way since the ISP is the company that provides you with internet access. Your ISP will then forward the packets to the VPN provider which in turn will forward the packets to their intended destination.
@@PowerCertAnimatedVideos I want to become a member and learn that kind of a video making...Please guide me with the link of that video and joining your channel also..
Sir, we have to say thank you for this VPN-based video, perfectly explained, just have one question is real that ISPs does not reach our web search via VPN? and does ANTI-Virus software's VPN include to paid VPNs, or VPN has to be bought from additional vendor for this purpose?
I don't understand your first question. Some antivirus programs have a built-in VPN, but that depends entirely on the software and/or subscription in question.
No matter what it's about a chain of trust. So you have to ask yourself who do you trust more. Your ISP or VPN provider. No way around it.....except Tor, but that's a whole different thing.
Hi sir, i am from India..Your videos are Excellent. your way of teaching is awesome easily understandable.But one thing i request u to Please make Video about OSI and TCP/IPmodel..
Not certainly. Though with SSL/TLS certificates your data are encrypted before leaving your device (mobile or phone), with a hacker being able to capture these data, he can perform rather bruteforce attack to crack these data. Obviously, most valuable part is the password. But, to be honest, I am not really sure, if the encrypted data are one continuous pile or it can be distinguished.
I'm glad to find your comment. After doing some research here and there (a lot of googling) I came to the same conclusion as you. That means, if you are at home with your own private network (wireless or not) and you are visiting HTTPS sites, your traffic is already encripted. So if you only care about security (when doing online banking) and not about hiding your identity nor location, then a VPN is not necessary.
@1:09 "By using a VPN, your on-line activity will bypass your ISP's server, and will be redirected to another server, which is a VPN server.". Well, sort of, but... You are not bypassing your ISP's server. 100% of your internet activity is still going through your ISP's server. The difference is that your ISP's server can no longer see what you are doing, even though 100% of your data is passing through their server. This is because your data is being encrypted on your local computer, and gets decrypted by your VPN's server. Any and all computers between you and your VPN service will only pass along the encrypted data, and will not be able to see anything other than scrambled data. @3:07 "So any activity that you do on the internet, such as visiting web pages, or transferring files -- the data is encrypted, and kept private, when using a VPN". Your data is encrypted, only between you and the VPN's server. Once you data reaches your VPN's server, 100% of your data is decrypted by your VPN service. The VPN service can see 100% of your activity, in the clear. So your data is not kept private, when using a VPN service. You are trusting your VPN service to do the same thing as what your ISP does. By using a VPN service... all of your internet activity will stop being visible by your ISP, and will now be visible by your VPN. You have simply handed your trust to a different company -- a different group of complete strangers. @5:34 "It reassures that you are surfing the internet safely, securely, and anonymously". If you visit sketchy sites, a VPN service will do zero to protect you. You will encounter malware, viruses, etc, the same as if you were not using a VPN service. The VPN service is simply acting as a middle-man. The VPN service does not interfere with what you are doing. The VPN service will pass along anything and everything, including malicious data. As to "anonymously", that is true, only if your VPN service is telling the truth. Lots of VPN services claim a "No logs" policy. They can claim anything that they want, because you have zero ways to verify their claims. They could be logging everything that you do, and you will not know, and you can not know. And even if a VPN service really abides by their claim to keep no logs... If they are handed a court order to keep logs, then they are going to keep logs. And if they are also handed a gag order, then they will not be allowed to reveal that they are keeping logs. What better place for governments to spy on people, than via VPN services? Using a VPN service is announcing that you really, really, really, want to keep your on-line activity private. That is where governments really, really, really, want to see what you are trying to keep private. If you think that your VPN service is really keeping your on-line activity private, you will have a rude awakening if you use a VPN service and engage in illegal porn distribution, or if you post that you are going to commit violent crimes (the type that puts you behind bars for life), etc. Watch how quickly you will get a visit from a government agency. @6:33 "But paid VPNs are more secure. These, generally ,will not log your internet activity, and they will keep it private". @6:49 "...and they have a strict, 'No logging' policy". As I wrote about above... you have zero ways to verify any VPN's claims. Also note that many countries have reciprocal law enforcement agreements. So if country "A" asks country "B" to keep logs, then they will comply. That goes for court orders. Look up "five eyes" and "fourteen eyes". Each set of eyes refers to countries that cooperate with one-another. Use a VPN service for accessing services that your county does not permit, or in a coffee shop on public WiFi, or to connect to your office. For all of those uses, a VPN should be safe and secure. But for general internet activity, using a VPN service is putting all of your eggs in the VPN's basket, instead of your ISP's basket. I am dismayed that our host made VPNs sound like the holy grail of security and privacy. They are not, and he knows it. If you want that level of privacy and security, then use TOR browser via the TAILS operating system, or via ParrotOS and its Anon Surf feature, or via Qubes OS, and one of its TOR related virtual machines.
Seems like you know what you are talking about. I have a question I would like to see if you can help me with. What is the best way to mask my location, put is as it am working from the US. Is it using a vpn? And using their server or perhaps doing that and then adding the static ip address that NordVPN offers? Or is it by setting up my own vpn server in a location where I want my ip address to be giving that location from and connecting to that? Can you give me a clue. It would be for work, and know the laws and I know I should let my employer know. I know the ethics of it in other words. But can you help me on it, some serves will block access if they detected a common sever right? Can a vpn use to access an employer vpn? Its is all in the router? Asus rog ax5400 to? Or ExpressVPn aircove?
Good video, the question is why I should blindly trust a vpn provider more than my local isp provider, there is no guarantee about how they use my information, at least my provider is in my country and is subject to known laws, but what about vpn providers located in certain countries that don"t care about privacy or personal data ? I never use public wifi, roaming or a brand new sim card is more secure and afterall we can survive without being online all the time
Most devices that support network connections support VPNs out of the box. However, some VPN services require specific clients to be installed in order to use the VPN. There are more advanced setups where you can set your router to use a VPN connection so any device that connects to your router automatically goes through the VPN.
also, is VPN an application or a programme? where would I download it? is there a charge for downloading? about how much is the subscription fee? is the information here still valid or has it been superceded? has this got anything to do with this new chatgpt I'm hearing about?
Too many questions. It has nothing to do with ChatGPT. That's a completely different thing. VPN is a protocol used to connect 2 or more network sites together. Let's say you have a business with multiple branch offices. They all need to talk back to a headquarters. You can setup VPN connections at all branch offices so that all the traffic goes through the main headquarters. In another example, if you are a remote employee, you may have VPN access to connect to your company's network over the VPN connection so that you have the same level of access remotely as if you were in the office. That's the purpose of a VPN. However, the term VPN is also used to promote VPN services. There are companies offering VPN services to customers by promoting privacy or getting around Geo-restrictions. This is what a lot of average computer users think VPNs are. That is technically true, but it isn't the entire concept. With these services, you pay for a subscription and get access to the VPN's service. How you get access depends on the service, but you usually download a VPN client or configuration file and import it into your client of choice and then connect to the service. Your traffic will be tunneled through that connection so your internet activity will appear to come from that area. In other words, if you live in San Francisco, CA, USA and use a VPN service in Guadalajara, Jalisco, Mexico, your internet traffic will appear to whatever websites you visit to come from Mexico instead of the USA.
Does Nordvpn have servers in South America? Specifically Colombia and Argentina? The main issue with many VPNs is that their servers in other countries other than England or mainland Europe is very limited. Thank you for you great and easy to understand IT video presentations.
Generally, proxies offer quicker connectivity than VPNs because they route only specific types of traffic, while VPNs encrypt all internet traffic, potentially causing delays. Zeus Proxy excels with its rotating residential proxy, perfectly suited for activities like e-commerce multi-account registrations, data crawling, airdrops, and gaming.

Is there any way that I can activate the Mobily device and do away with requiring the second STC router ?
Great videos, may I know what software do you use to create those amazing animated videos. Thanks
Thanks. Powerpoint
Thank for your explanation. I have a question,Do the packets go directly to the VPN server or they go first to the ISP server and then routed to the VPN server?
They have to go through your ISP first. There's no other way since the ISP is the company that provides you with internet access. Your ISP will then forward the packets to the VPN provider which in turn will forward the packets to their intended destination.
this one could use a follow up with more detail around how the encryption/tunneling works, at least practically
The mug of coffee was really cool.
Thanks for the awesome explanation.
Which software/tools do you use to create such animation....I want to learn ....Please reply
Powerpoint
@@PowerCertAnimatedVideos I know how to use basic power point. But to create such stunning animations. Could you please make videos on that...
There is a video about how I do it, available for members only. It's basic...but I may do another one in the future.
@@PowerCertAnimatedVideos I want to become a member and learn that kind of a video making...Please guide me with the link of that video and joining your channel also..
There should be a "join" button on each video next to the subscribe button. If you don't see it then youtube hasn't enabled members in your area yet.
Thank you for another great video.
Sir, we have to say thank you for this VPN-based video, perfectly explained, just have one question is real that ISPs does not reach our web search via VPN? and does ANTI-Virus software's VPN include to paid VPNs, or VPN has to be bought from additional vendor for this purpose?
I don't understand your first question. Some antivirus programs have a built-in VPN, but that depends entirely on the software and/or subscription in question.
Even the VPN providers can have our original IP and can share with government or companies right?
Yes...if they chose to. But they are not supposed to if it's in their terms of service.
@@PowerCertAnimatedVideos so it's like trying to be secured in an unsecured environment 😂
This is how data is shared and miss used
@@yashsakhare5399😅😅😅
No matter what it's about a chain of trust. So you have to ask yourself who do you trust more. Your ISP or VPN provider. No way around it.....except Tor, but that's a whole different thing.
I get so excited for each new video. As usual, great video
Yeah, me too.............these videos are pure gold.
Glad to hear it!
Hi sir, i am from India..Your videos are Excellent. your way of teaching is awesome easily understandable.But one thing i request u to Please make Video about OSI and TCP/IPmodel..
Good one... Simple to understand...❤
Great explanation. How do you know the VPN isn’t logging your activities?
Exactly!
What guarantee is there that the ISP hasn't set up their own VPN? Or that the VPN you've chosen hasn't made deals to sell your IP?
A well explained video on what VPN's are. I especially liked the Hacker in the coffee shop. Nice touch, PowerCert
Thanks! 😃
how good is Tailscale in use ?
Please make a video about CORS and same-origin policy!
Just a note. Even if you pay for a vpn, they still may sell your data and i doubt that nordvpn don't log your activity.
Very true! , gain your trust then do as the free vpns do, sell your data 😚
does this mean I can only use this VPN on a laptop? It would be more useful on my tablet so I can stream it to my smart tv
Is the burning coffee pot a result of the HTCPCP(Hyper Text Coffee Pot Control Protocol) implementation?
good one :)
If the site has SSL enabled, you should be safe using public Wifi (unless it is a compromised connection). You only need a VPN to hide from your ISP.
Not certainly. Though with SSL/TLS certificates your data are encrypted before leaving your device (mobile or phone), with a hacker being able to capture these data, he can perform rather bruteforce attack to crack these data. Obviously, most valuable part is the password.
But, to be honest, I am not really sure, if the encrypted data are one continuous pile or it can be distinguished.
@@andrejpovala bruteforce is practically impossible and takes years for a string of 8 charectors
I'm glad to find your comment. After doing some research here and there (a lot of googling) I came to the same conclusion as you. That means, if you are at home with your own private network (wireless or not) and you are visiting HTTPS sites, your traffic is already encripted. So if you only care about security (when doing online banking) and not about hiding your identity nor location, then a VPN is not necessary.
can you make a video about routing tables please!!🙏🏻🙏🏻🙏🏻
you missed out part where you can create a vpn server by yourself with openvpn in cloud/home server.
Does your internet become slower using a VPN and what about a router VPN?
I connect to another mac - would we both need to have VPN access?
Can you circumvent the European Digital Services Act with a VPN?
Thank you, teacher, really you explain very very well, and thanks very much for turkhis subtitles
Hello Sir,
Which software is commonly used for animation?? Please named it.
@1:09 "By using a VPN, your on-line activity will bypass your ISP's server, and will be redirected to another server, which is a VPN server.".
Well, sort of, but...
You are not bypassing your ISP's server.
100% of your internet activity is still going through your ISP's server.
The difference is that your ISP's server can no longer see what you are doing, even though 100% of your data is passing through their server.
This is because your data is being encrypted on your local computer, and gets decrypted by your VPN's server. Any and all computers between you and your VPN service will only pass along the encrypted data, and will not be able to see anything other than scrambled data.
@3:07 "So any activity that you do on the internet, such as visiting web pages, or transferring files -- the data is encrypted, and kept private, when using a VPN".
Your data is encrypted, only between you and the VPN's server. Once you data reaches your VPN's server, 100% of your data is decrypted by your VPN service. The VPN service can see 100% of your activity, in the clear.
So your data is not kept private, when using a VPN service. You are trusting your VPN service to do the same thing as what your ISP does. By using a VPN service... all of your internet activity will stop being visible by your ISP, and will now be visible by your VPN. You have simply handed your trust to a different company -- a different group of complete strangers.
@5:34 "It reassures that you are surfing the internet safely, securely, and anonymously".
If you visit sketchy sites, a VPN service will do zero to protect you. You will encounter malware, viruses, etc, the same as if you were not using a VPN service. The VPN service is simply acting as a middle-man. The VPN service does not interfere with what you are doing. The VPN service will pass along anything and everything, including malicious data.
As to "anonymously", that is true, only if your VPN service is telling the truth.
Lots of VPN services claim a "No logs" policy.
They can claim anything that they want, because you have zero ways to verify their claims. They could be logging everything that you do, and you will not know, and you can not know.
And even if a VPN service really abides by their claim to keep no logs...
If they are handed a court order to keep logs, then they are going to keep logs. And if they are also handed a gag order, then they will not be allowed to reveal that they are keeping logs.
What better place for governments to spy on people, than via VPN services?
Using a VPN service is announcing that you really, really, really, want to keep your on-line activity private. That is where governments really, really, really, want to see what you are trying to keep private.
If you think that your VPN service is really keeping your on-line activity private, you will have a rude awakening if you use a VPN service and engage in illegal porn distribution, or if you post that you are going to commit violent crimes (the type that puts you behind bars for life), etc. Watch how quickly you will get a visit from a government agency.
@6:33 "But paid VPNs are more secure. These, generally ,will not log your internet activity, and they will keep it private".
@6:49 "...and they have a strict, 'No logging' policy".
As I wrote about above... you have zero ways to verify any VPN's claims.
Also note that many countries have reciprocal law enforcement agreements.
So if country "A" asks country "B" to keep logs, then they will comply. That goes for court orders.
Look up "five eyes" and "fourteen eyes". Each set of eyes refers to countries that cooperate with one-another.
Use a VPN service for accessing services that your county does not permit, or in a coffee shop on public WiFi, or to connect to your office.
For all of those uses, a VPN should be safe and secure. But for general internet activity, using a VPN service is putting all of your eggs in the VPN's basket, instead of your ISP's basket.
I am dismayed that our host made VPNs sound like the holy grail of security and privacy. They are not, and he knows it.
If you want that level of privacy and security, then use TOR browser via the TAILS operating system, or via ParrotOS and its Anon Surf feature, or via Qubes OS, and one of its TOR related virtual machines.
Agreed. The diagram makes viewers think that they are going direct to a vpn when they are still routing through their ISP.
Seems like you know what you are talking about. I have a question I would like to see if you can help me with. What is the best way to mask my location, put is as it am working from the US. Is it using a vpn? And using their server or perhaps doing that and then adding the static ip address that NordVPN offers? Or is it by setting up my own vpn server in a location where I want my ip address to be giving that location from and connecting to that? Can you give me a clue. It would be for work, and know the laws and I know I should let my employer know. I know the ethics of it in other words. But can you help me on it, some serves will block access if they detected a common sever right? Can a vpn use to access an employer vpn? Its is all in the router? Asus rog ax5400 to? Or ExpressVPn aircove?
Good video, the question is why I should blindly trust a vpn provider more than my local isp provider, there is no guarantee about how they use my information, at least my provider is in my country and is subject to known laws, but what about vpn providers located in certain countries that don"t care about privacy or personal data ? I never use public wifi, roaming or a brand new sim card is more secure and afterall we can survive without being online all the time
Its amazing, well explained in 7 minutes
Hello sir I hope you can make a video explain what is integers range in a computer ❤❤❤ I am a BSIT 1st year student
Does a VPN cover 1 device or multiple ?
I hope you make a video on Graphics cards!
Can you make a video of what's the difference between VPN vs Proxy
Nice explanation. Often a VPN will really slow down your thruput. Often a trade off between safety & speed.
Yes, true
Are VPN's device specific as in do you need one for a phone and another for a laptop etc
Most devices that support network connections support VPNs out of the box. However, some VPN services require specific clients to be installed in order to use the VPN. There are more advanced setups where you can set your router to use a VPN connection so any device that connects to your router automatically goes through the VPN.
also, is VPN an application or a programme? where would I download it? is there a charge for downloading? about how much is the subscription fee? is the information here still valid or has it been superceded? has this got anything to do with this new chatgpt I'm hearing about?
Too many questions. It has nothing to do with ChatGPT. That's a completely different thing. VPN is a protocol used to connect 2 or more network sites together.
Let's say you have a business with multiple branch offices. They all need to talk back to a headquarters. You can setup VPN connections at all branch offices so that all the traffic goes through the main headquarters. In another example, if you are a remote employee, you may have VPN access to connect to your company's network over the VPN connection so that you have the same level of access remotely as if you were in the office. That's the purpose of a VPN.
However, the term VPN is also used to promote VPN services. There are companies offering VPN services to customers by promoting privacy or getting around Geo-restrictions. This is what a lot of average computer users think VPNs are. That is technically true, but it isn't the entire concept. With these services, you pay for a subscription and get access to the VPN's service. How you get access depends on the service, but you usually download a VPN client or configuration file and import it into your client of choice and then connect to the service. Your traffic will be tunneled through that connection so your internet activity will appear to come from that area. In other words, if you live in San Francisco, CA, USA and use a VPN service in Guadalajara, Jalisco, Mexico, your internet traffic will appear to whatever websites you visit to come from Mexico instead of the USA.
Which is safer?. ISP or VPN server??. What is the guaranty?
Great illustrated
We need to know how to establish VPN connection for Free!
Does Nordvpn have servers in South America? Specifically Colombia and Argentina? The main issue with many VPNs is that their servers in other countries other than England or mainland Europe is very limited. Thank you for you great and easy to understand IT video presentations.
Yes. They have 10 servers in Columbia and 9 in Argentina.
Generally, proxies offer quicker connectivity than VPNs because they route only specific types of traffic, while VPNs encrypt all internet traffic, potentially causing delays. Zeus Proxy excels with its rotating residential proxy, perfectly suited for activities like e-commerce multi-account registrations, data crawling, airdrops, and gaming.
Thank you sir 🙏
If I connect to a website using https through a public wifi, is my data still at risk?
