This is super nicely explained. But something is missing. I know youve been giving great examples here and there. But for example, why its important to know the difference between UDP and TCP. Is udp more pro ne to the man in the middle attack? Are tcp and udp used together?.. etc. But again, super well explained video. Just which there was ab example of possible weaknesses and real life examples to everything
I learned on my own while in college along with Linux/Unix back in late 90s. Never went to school for that (was meteorolgy major) and got into my job (networking) without any degree. Was all self taught. Word of advice being in school for it. Set up home labs and break your labs and fix them. Academia is nice, but get practical HANDS-ON experience. Do volunteer work in low budget areas like a church or private schools to put this as experience kn your resume. I value experience > formalEducation. Also, when you mess up and learn in your labs you get to.undetstand more about how things work when yoi troubleshoot. Just some advice from someone who has been in networking and systems administration for 24 years on June 5, 3 weeks away.
@davebukowski i agree with you. Would you mind recommending youtube channels to create the correct foundation of a network engineer? Appreciate your reply
Please, can you tell me where I can build a free network lab for practice? I tried CISCO but they are asking for payment for their network packet tracer or something
I dont understand why people making fun of the voice ? This video was better than all the other videos iv watched from others. I was ready to give up till I seen this video...
honestly couldn't find a better crash course to get started on hacking after networking. thanks bro you explained this better than network chuck at some points ❤❤
Correct me if I'm wrong but you can't really use NAT without PAT, because NAT translates a unique private ip within a LAN to one public ip to reach the internet. But when the data is to be returned to the original machine, PAT is what makes sure it goes to the right machine.
Thanks for explaining these terms in a way most people can understand! Even after four years of majoring in cyber security, I've always felt lost with these terms, and the lectures didn't help at all. I found this video while I was preparing for a job interview! Anyway, thanks a lot!❣
I’ve been watching your videos for about a week always had a passion for things like that and gadgets also recently ordered some what you recommend on a couple of your videos I watched
This is priceless, this is exactly what we need. Someone who can explain basic and abstract concepts in a helpful and easy-to-understand manner. Congratulations, my friend, you've gained a new follower! Please continue to bring more content like this. Btw, excellent pronunciation for a non-english speaker. Thanks!
Thank you! I think I will need to rewatch this a few times, but I feel a wrinkle slowly growing on my brain :D I am definitely looking forward to seeing how to use the protocols to understand and analyze the Wireshark data better.
If the communication inside Ethernet protocol is made through ARP, linking the IP with MAC, why is IP important inside a LAN? Because, if you want to send a message to another node, could I send it directly to the MAC address instead of using the IP to look for the MAC?
Oh, that is a good question bro, IP is important inside a LAN because: It enables devices to communicate within the LAN and with external networks, It allows for network segmentation and routing decisions, It provides a logical addressing scheme that is easier to manage than MAC addresses, It supports compatibility with various network protocols and services.
Amazing video!! Now networking protocols are getting cleared. On how they work in the real-world. Amazing content. I must say that it was a channel which has to get subscribed by everyone.
this is the best video explanation i have ever seen even my teacher couldnt explain for me to understand it as better as you did . i have subscribed and saved your video and i am hooked to your channel
@@MohammeddAlanazi yeah it's so convincing right? Nowadays you can only tell by the really small stuff like the "person" speaking seemingly not experiencing emotions, but there are even better tools that can imitate that and it's very disturbing
This was pretty greatand elaboratove (coming from someone who already knows this stuff); I'm just saying, good job on clarifying the actas of a few protocols that most don't quite make clear. Nice work, AI.
Thank you for videos like this. Currently taking courses online to receive my associates in cybersecurity but I have to admit reading some of the material can be a snooze fest! Much appreciated ❤
11:05 I thought that the DHCP is the one assigning the IP addresses when a new device joins and the ARP is what's used to match them each time after that.
Im completely new in the field, baught a bunch of books, still have to read them all 😅 but i do find it interesting currently im still working through my a smarter way to learn python and computer organisation. What i really hate about the I.T world is that there is SO MUCH TO LEARN that you dont really know where to start.
Great video but what happened at 6:08? You said third row but talked about identification, flags and fragment offset which is actually row 2. You then went to source and destination address without talking about the real row 3. I heard no mention of time to live, protocol or header checksum.
Hi, Very nice video and straight to the point, i would like to see a video about every details on every layer and protocols(stack ISO/OSi :) ... Nice @HackerJ
What irks me about most IP address tutorials is the fact that they neglect to mention that IP addresses are assigned based on context. Every time your device connects to the internet, it does not get the same address, therefore the "house" analogy fails to clarify this very important piece of information. It is more like getting assigned an order number or table number at a restaurant. If you go to another restaurant, you get a different number. It is based on the context/situation.
A home router will have the same IP address for a while until the ISP decides to attribute you another one. So for reaching your home network, the house analogy still stand
My fav analogy is the house analogy where the IP address is the residential address, but there is also the MAC address where in the analogy is represented by the recipient of the letter.
Thank you for doing such a beautiful job of explaining in terms that I was able to understand I know absolutely nothing basically so thank you so much🎉🎉🎉🎉

Telnet still widely use in controlled or isolated environment .... such as P2P devices ...
11:05 I thought that the DHCP is the one assigning the IP addresses when a new device joins and the ARP is what's used to match them each time after that.
that's correct. DHCP assigns IP addresses to new devices in network. ARP resolves what MAC belongs to IP, when devices want to communicate.
