"If you want me to do a video on ipv6, let me know in the comments below"
everyone: *I N V E S T*
Tf we need a video on IPv6 for? The amount of addresses is in the undecillions. We could colonize Mars and have 20b people on each planet with 50 uniquely addressed devices each and still have plenty of address space leftover.
IP Version 6 have some privacy alarming features like identifying the device use the address, since there is such large possibility that each device can be used with it's mac address to assign ip6 address.
I want to see an IPv6 video. For a coding project in school I used nslookup to query 1 million URLs and collected the IP addresses... I got a 100% on that project btw XD.
What did you do with the IP addresses? Look up their location and find where the most websites are hosted or something else?
@@laurinneff4304 Nah, I kept them in a txt file, and it's a backup in case DNS goes dark or I want to eliminate DNS from the puzzle for some reason.
@@greatcanadianmoose3965 that list would be mostly useless as a lot of major sites have dynamic ip’s that change every so often, on top of “serverless”/ cloud based services.
I thought of making something similar, but accounting for someone else’s dns record to create your own is self defeating, you could make your own domain registrar, that could be a nice business to have.
@@egg5474 Out of curiousity, how often do these websites change IP addresses? On a daily basis or multiple times a day?
@@greatcanadianmoose3965 From what I’ve seen it’s typically less than daily, more so roughly around every two weeks, although that’s far from a definitive answer
I don't know why I like so much the videos from this guy
Yeah man that'd be cool if you get a video detailing all the specifics of IPv6!
I would in fact like a vídeo about IPv6 as it is often overlooked.
I'm actually quite curious about ipv6 as our networking class in college didn't really go too in depth into that either, and while i knew everything about this video already, it was great to have a refresher!
I definetly want to see a video on IPv6, even though I know all that was shown, its so much better to see someone present it with a proper mic and normal resolution. Instead of the ones used by my teacher.
Yes please do IPv6. For 20+ years I still haven’t grasp to full extend of IPv6 capabilities yet 😅
Yeah, an IPv6 lecture would be nice. Also you could mention that NCC ran out of new IPv4 addresses already and thus how a transition to IPv6 will be done.
Omgg, that is a really great video. Thank you! S2
The mailing address analogy was helpful!
Spoilertip: We already ran out. At the highest level at least.
Actually it would be pretty nice if you did a video on ipv6. This video was very good and explanative, and i think one on ipv6 would be useful aswell.
IPv6 video would be great
Thx for the content
I don't think my small brain can actually comprehend this. Not because I'm watching this in the dead of 12 in the morning, but I'm that dumb.
oh right ports, that's what they didn't teach me at my formation center, I was sure that I was missing something!
I'd love an ipv6 video!
A video about ipv6 would be nice
I'd love to see video about ipv6. It's a little more complicated than ipv4
If both PCs have the same port and connect the same website (let's say the port is 8899), how will the router know who 55.66.77.88:8899 is for? I think the router will change the application port to something that is actually unique (example 8899 for PC1 will be mapped to 10000 and 8899 for PC2 will be mapped to 10001) and the router will use 10000 and 10001 when communicating with the server. So 55.66.77.88:10000 will be for PC1 and 55.66.77.88:10001 will be for PC2
hey mo, what do you do for a living?
what's the difference between 192.168. ... and 10. ... local ip address
@@trp225 huh. thats neat, i always wondered why enterprise, school, and proper networks used 10. for its subnet mask

what about mobile conections like 4G?

Is dhcp related to static ip address?

@@nathsabari97 it is related to dynamic ip adresss
no its not related to static ip if you want to have static ip you need to set one manually either from the router or if its a switch which also has dhcp you can set a static ip from your pc/server

IPv6 has always been a mystery for me.
I must say, once it finally clicks you start to complain about how convoluted and unnecessary NAT actually is... Why don't all my devices just have a public ip address?? With ipv6 they do, that's so much more useful!
@@supernenechi does all isps support ipv6?
Still is
@@tacticalguy6473 Nope. Really depends on your area. Most of the far developed countries who pioneered the Internet in its early years have claimed very large chunks of the ipv4 address range. That means that The US and EU countries will mostly still run on ipv4 alone. A lot of countries that are only now really booming in Internet usage can barely get ipv4 addresses and have to resort to using ipv6 exclusively. There are ways to visit ipv4 only domains and services through ipv6 however, but it would be more useful to just completely abandon ipv4 today and move over now.
These days almost all ISPs in developing countries offer ipv6, mostly because they can't avoid it. ISPs where I live (The Netherlands) have been extremely reluctant to even try ipv6. At least now here more and more ISPs are using ipv6 as well, alongside ipv4. Meaning every device in your network will use IPv6 if they can, but ipv4 is they can't.
It's rather pathetic how the world has actually run out of ipv4 addresses meanwhile we're all sitting here screaming how we are running out. We are not running out, we have run out already years ago and we're working around IPv6 like it's the plague.
@Fashinqu A. Like I said in another comment. Depends on your country and ISP. Some offer it by default to everyone, some only have ipv6 and some just don't give a damn
"We shouldn't be running out opf ipv6 adresses for the forseeable future"

ipv6 is surprisingly easy to grasp, its NDP and SLAAC that throw me off
Going into cyber operations here, 4:25 gotta do it on the daily, I hate myself and life.
DUDE its so funny you just made this, I literally the other day was explaining to someone who asked me this question, your explanation was a lot longer and more detailed I didn't feel like explaing it to the script kiddy because he wouldnt of understood anway so I said in short, don't worry we have IPv6 on backup and o yeah ipv6 can have over 340 UNDECILLION address, and yeah also told him to do some calculations himself for class a class b class c and basicalyl there is atleast over 4.6billion address, and then i stopped and just said GO TO ARIN or better yet do your own research this is why we are stupid now of days because nobody researches anything themselves they just listen to others and take it as gospel
calm down
Yea an IPV6 video would be great
New Gentoo optimizations, and other maintenance tips would be very welcomed =)
So when I look up my ip and I see that long mess, that’s just because it’s using ipv6 instead of ipv4? I always wondered about that
A good video that explains IPv6 in depth would be good
This is really good basics material for new tech users, especially for people that want to set up web servers on their home network
All praise NAT. May I never have to lay eyes on ugly ass IPV6.
Honestly. Something more minimal with no more than a trillion combinations would be more practical. You can even memorise an IPv4 address, so they're great for sharing your favourite game server
Actually not. NAT is a cancer. You can't receive incoming connections with it. So you can't host a server, can't be a host in case of P2P activity, etc.
If everyone will be under NAT you can forget about such things as self-hosted servers and all P2P services. That means no torrents, no private decentralysed networks etc. Only corporate-ruled servers. Think of it.
@@username6338 yeah, there actually more tricks. Like UDP hole punching / STUN tunneling. But such tricks works only with certain NAT types, so ISP can easily block it or switch to restricted NAT. Also this is still just a trick, very unreliable, there are almost no real software that relies on such things.
@@mk72v2oq Ikr, my ISP charges for personal ip adresses and im stuck with cgnat - giving me limited access to features of online games
@@NyunProduction yep. I'm also paying extra for dedicated IP address.
Then I ask the big question: Why is it 192.168.x.x
Waiting for ipv8 with 512-bit long addresses
This like saying why we can't run out of numbers
Ipv6 video pls
Ipv6 video pls
I'd like to know more about IPv6 and maybe how I could make my code compatible with it
Really great explanation, I especially liked that mail analogy
well ipv4 is soon to be out of address anyway (or already has?)
Since im playing ps4, i always learning about network. I don't understand why ps4 need NAT 2 for connecting but steam (pc) allowing people to connect without warning that they are using NAT 3. But as result i play better connection with people in ps4 than pc
What is your take on ISPs NATTING WAN connections, i.e. even the WAN port of our router doesn't get a public ip effectively NATTING connection twice
We need that
Btw remember the good old days of traditional online games where we share ip adresses to LAN together?
Because they keep getting recycled every time a hacker gets blocked and can't get through they dump the IP address and get a new server, then when I get a server I get those IP addresses and now my server can't send mail because it's blocked everywhere.
That's the address to an actual google server.
IPV4 vs V6 is basically the difference of finding out you underbuilt (raw IPV4), patching the problem by splitting its workload (Network Address Translated IPV4), then going and massively overbuilding a replacement (raw IPV6), then applying the same patchwork to the replacement (yes, IPV6 can be run in a NAT, I don't know why).
well well well...
lol, you think NAT is the solution, while IPV6 is the solution and nat is only temorarily a "fix" and even with that 'fix' we're already running out... i remember the days that i had fixed ip adresses and got 2 ip's for my dsl connection (i could make 2 PPPOE connections on a single line/modem), nowadays fixed ip's are expensive. how do you run multiple webservers with NAT from a single ip which each are reachable by just typing in the domain name in the browser? NAT can't solve that... also, ipv6 is far from new nowadays, 10 years ago, then it was still considered 'quite new", but today most isp's are already running dual stack and i've even seen providers that only give out an ipv6 address and rely on 4-to-6 translation on the endusers side to reach ipv4 networks... once you get ipv6 you can throw NAT overboard and give each device you want world-readable access so it can be reached on the correct port for the protocol; so with my ipv6 range (which is fixed btw!) i can run more dedicated webservers with their own public ip-address than ipv4 could ever deliver, even a million times over. And yes, some people are so stupid that they disable ipv6 in their networking settings because they think it uses more resources, which is nonsense and it will only see those people having more and more issues with being unable to reach certain services.
IPv6 is slowly making some ground. Cell carriers are moving pretty quickly with it which is good. IPv6 always makes me uneasy knowing this laptop for example gets it's own IP over my router and NAT doesn't exist in between. I like that NAT layer.
I've understood this, but there could easily soon be more than 3.7 billion routers and unique addresses. I understand IPV6 is supposed to address (heh) this, but how exactly is this done? How are unique IPV4 addresses managed to prevent conflicts?
So if nothing changes but the ports how does that fix the issue of PUBLIC IP address? I just don't get it lol, also why did he talk about double stacking and many other things that help extend the available ip addresses.. india actually ran out almost at one point. If this video was true all they had to do was buy more routers and change the PORT? Lol.. I'm sorry someone has to say something
I'd be interested in a vid about ipv6.
Thanks for continuing to put out informative but understandable content!
If 192.168.etc is only for private networks then why is does mine start with those numbers? It shows this number on my phone and Ipad, they're connected to a home wifi router. Nevermind, I didn't watch the full vid lol
4:26
I made dhcpcd use a static IP adress for my PC. I had to do it because my PC is a print server, and I couldn't manage to print from my phone using the PC's hostname (probably would have to use mDNS, but I don't know how to set it up, and using a static IP is easier)
Yes! ipv6 video! You explain really well, thank you very much!
Completely misleading.
You even mention that there is finite address space.
NAT does not increase a finite space. And the private addresses space classes you immediately follow up with are what are used to NAT between Internet and private networks.
However, NAT is not needed for this. Routers help here.
Will not watch past this point because this is literal hot garbage :45 seconds in.
Becuse every ISP in Turkey uses CgNat. One I wanted to open an OpenVPN server and the router warned me that the server would not accessible from the Internet. Called my ISP about it I had to have to play 25€ for a IP address.
How should I use my computer? I'm a normal person on Windows using Google Chrome, but I'm interested in computers and these videos seem to tell me that this is the wrong path to choose.
"Mailman doesn't care about the name"
You didn't meet my mailman, he knows exactly who isn't home even tho we don't know where he is.
Perhaps I'll have to tell ppl to stop sending mail and start sending me email that I'll never check
would be really nice if you make a continuation talking about cgnat, thanks for the great video :)
Carrier grade NAT is basically the same thing, just on an ISP level where your router gets a "private" IP in the ISP's network and the ISP does NAT to use a single public IP for thousands of homes
Don't forget about my personal enemy: DS-Lite
Oh hai there super fast A/C wifi AP! Hope you like 802.11b, cuz we all gonna be speaking 802.11b as long as I am around.
why don't we just use ipv6 is the real question
Like with most technology there's going to be legacy users for ipv4 for a long time to come.
@@MentalOutlaw Aren't they compatible? I thought it was an 'infrastructure' problem: the big players not caring enough to make the switch.
because only 1/3 of the internet had adopted it: www.google.com/intl/en/ipv6/statistics.html
Also so much software is written on the assumption that you're using ipv4 I don't think it's ever going to fully go away.
@@ThibaaauuulT You can place a IPv4 address inside of a IPv6 address to as a backwards compatibility option for IPv4 only devices, another device like a router is needed for the IPv4 in IPv6 conversion.
ergo creation of IP6. A number so large it provides several hundred thousand address's for every square meter of surface of the planet. So until we have lots of planets probably not be a problem. if not then IP7, 8, , , , , ,
in asia, ipv4 addresses actually have been run out :( here in pakistan all isps are adopting cgnat, usually its not a problem but cgnat doesn't allow port forwarding, there is some sort of protocol, called port control protocol which does enable people to use upnp on cgnat but its not used by our isps, so situation is pretty shit, can't even host counter strike servers without paying/vpn server
I want a video that's all about IPv6.
Also thank you very much for making this video.
But we do run out of IPv4 addresses...
well yes... but slower.
@@Radovanslav did, we had already ran out long before this video was made.
I never thought of how hard that router can work supplying ports for all the seperate data streams! Cool...
We did run out of 32 bit addressing. IPv4 exhaustian! Its only with IPv6 that has saved us.
Now lets block the backend firewall all ports and tunnel into a vpn with no logs and DDOS protection with clean name services
We need an IPv6 video.
I'd like to see a vid on IPv6 as well
Blocks out the names of the devices, but doesn't block out the MAC address, kinda defeats the purpose
We do, that's why we're getting IPv6
Is your answer subnet masks? That would be lulz
Because people are dying as we speak. You could be using Ip address of a deceased person.
Ipv6 adresses are infinite.
Yes a video of IPv6! Explain what the hell is IPv6 4? Spyware
As someone who is employing friends who dont know what a bios is, this is definitely going to be one of the videos that I have them watch before I have them do anything. Thanks for the excellent explanation
