Yeah, Spain too brother, Spain too... At least I can get an IPv4 with no CG-NAT, whiiiich is arguably better even... or more legible at the very least... Sucks I can't host shit over IPv6 tho
THANK YOU for finally making a video about the internet that also covers IPv6 and doesn't say, "This is some other different thing, you don't need to know about that" I have waited SOO LONG for someone to make a video that isn't just IPv4
When I was working as a technician for an eSports streaming company, we had 3 small servers around the globe to route traffic through or use for some other needs. Since we were often receiving an RTMP or other stream from across the pond or even from Japan to Finland, there were times when the route just wasn't optimal with direct routing, so if we chose to route the RTMP traffic first through one of the servers that were located for example in Germany, we could quite often "force" a better route and get good and stable stream :) but the truth truly is that nobody knows how internet actually works, and that's the whole point :D Packets somehow get where they're supposed to get... most of the time. But with video streaming etc. you might not be able to wait for the packets, so you need to get more creative :)
this reminds me of the time when me and a friend were trying to play minecraft together. i hosted the server and forwarded the port, it worked beautifully. my friend who lived a town away, however, had THE WORST connection ever to my server. i'm talking so much packet loss it was just unplayable. so on a whim, i decided to do an experiment. i used a digitalocean droplet that i was renting from toronto (quite the distance away from us both, but still same country/province) to set up an SSH port forward back to my server at home. lo and behold, when he connected through the ssh tunnel, his connection was miraculously 100x better, and he was able to play just fine. i love the internet
Fun fact: I finished editing this video in a train. All 600 assets were on my portable SSD, except for two voice takes, which DaVinci Resolve captured on the internal disk of my workstation at home... so I asked Tris for last-minute voice-over work and even though he was traveling, he obliged! (It's the second time he records something for me, unfortunately the first time, I ended up scrapping the whole video!)
I thought I was going insane for a second in the Polish segment. I could understand what you were saying but I had no idea why. It took me a few seconds to realise that you were speaking Polish. A very surreal feeling 😅 Your Polish is really good by the way.
It took me until 7:53 to realise you're french and that's why it was going through french telcos. This is without mentioning I've already watched 4 of your other videos
you meant DNS instead of NAT ;P NAT came way later, after there already were concerns about IP limits... oh and don't forget usa military and a few major companies own like half of ipv4 address space...
CANYON.MID!!! (at 0:58) Boy, that was probably the first thing my computer speakers ever put out - our family 386 only had an AdLib card at the beginning, so wav files were out of the questions, but MIDI playback worked. I must've listened to that song dozens of times as a kid.
Your videos are as good and as clever as your blog posts. Subtle smart remarks, very fun to watch. I knew all the stuff you showed but it was very entertaining. Cheers for that. I'm subscribing!
Excellent. Please always keep your silly and fun delivery. I can't believe I actually enjoyed watching the Brilliant advertisement. Educational and wildly entertaining, thank you very much for the video.
This video will be an excellent alternative entrypoint into the rabbit hole of having your own autonomous system, as a private individual, with your own IP space announced from it. I can feel it.
i dont understand people that say ipv6 is too complicated but use NAT and CG-NAT just to have some ipv4 addresses. I started calling ipv4 "legacy ip" and ipv6 just "ip"
Recently a technician from my ISP tried to convince me that almost no websites will work for me if I use IPv6 at home (let's skip the fact that I wanted to do dual-stack) and yet Google is reporting 50% of global traffic being IPv6 and mobile connections extensively use IPv6. The issue seems to be that a small group of people are stuck in the 90s refusing to even try to understand IPv6, but those people have a big influence on the network operations.
@@el_qubaI always heard it the opposite way, that if you host only on v6 that hardly anyone will be able to access it. Perhaps what he meant was few sites host ipv6, but 6to4 exists (which is why mobiles work), and it's less complex than NAT.
Loved this one, especially the subtitles 😂 simplest explanation I've seen that I'd feel confident I could show my parents and they'd understand. Thanks.
Have to say, I was impressed by both the French pronunciation and the Polish one (admittedly the former makes sense, but the latter I was not expecting)
The first time I watched the video I was barely familiar with networking mainly thanks to my attempts to host a Minecraft server during high school. It required the understanding of private vs public IPv4 addresses as well as some fiddling with port filtering on a router. So, at first a lot of moments such as protocol names and command examples just went over my head. But dude, I'm in the middle of a Linux + networking course right now and it all made so much more sense. I've been able to truly appreciate your work explaining the overall picture of the Internet. Followed through all the steps, looked up a bunch of mentioned topics, understood the commands, got all the jokes (they're great btw :), and finally the pieces are coming together. Although I wouldn't recommend this video to a complete newbie, with some level of entry knowledge it's top tier. Thank you, genuinely. Now everything is much clearer. I subscribed. Keep it up!
I went to school for networking and never ended up using it that much (moved onto cloud work, but again the cloud's foundation is networking i just work with L1 and 2 less ) so this was fun to watch.
Really enjoyed hearing noboilerplate in your Brilliant sponsorspot :) (I should probably finish the video before commenting, but if we also get a later cameo that'll be fun as well)
I really love this video. I have a slight understanding of how networking works so I was trying to guess where you were going next and was shocked several times at where you went with it. It’s very novel and I will be sending this video to people who are interested in learning (and some who are not)
Less snarkily, I self-host a few services for reasons, and this has become much better with IPv6 - because it avoids the indirection to the IPv4 address of the router when I'm actually home. On the local network, IPv6 is routed directly, which is a significant speed boost. (Still have to deal with dynamic dns and everything of course, yet still.)
I have DDWRT and OpenWRT on my routers for a reason. Having up to date firmware reduces the chances I'll be vulnerable to some random bug that let's someone into my network.
This is pretty good ! I would have added cable Internet, maybe ? Not just DSL. The US is at almost 50% IPv6 adoption though, so pretty much the global average.

Well, for UDP anyway, maybe not for TCP I guess ? 19:42 actually, the opposite is also true, see the talk: Freedom in the Cloud by Eben Moglen.
brother in christ you gave me a heart attack by randomly speaking in polish, i thought I'm either hallucinating or youtube randomly enabled a new ai feature lol
I've been scared of the inner workings of the internet up until watching this video. Without specific addresses in the examples I woudn't have enjoyed so much and understood so easily the content. So many educational videos give an overview the mechanism/protocol and don't go through it with specific numbers, which is useful for tracking what's going on. (on a small note, it's important to remember that sometimes being specific can cause people to draw wrong conclusions like when teaching geometry and more specifically properties of triangles)
Small thing but I saw at 14:42 that you are using an Ampere instance on Hetzner! I’m a logic design engineer there! What do you think? Any comments/complaints from making the switch to ARM?
As a software developer, this explains why I never had a clear understanding of IPv4. It's confusing as heck, and all you have to figure out what's going on is a bunch of tools that only give you partial information, and people can sit between you and your destination and modify your stuff. Amazing. I think I'll stick with my debugger that allows me to inspect the full memory of the program, pause, modify values in memory, hotload new code to fix a bug without rerunning the entire transaction, and jump to a previous line of code to rerun a previous method again, with different values. Being a network engineer sounds awful.
Great Video!! At 20:00 you mention a MAC-Adress to geolocation DB - what do you mean with that? I dont understand how that kind of Database would have any amount of usable data
So I was thinking of location.services.mozilla.com/downloads but upon closer inspection I see neither SSID nor MAC in there. Here's BSSID/SSID: github.com/GONZOsint/geowifi And I'm fairly confident other vendors track MAC, because it's uniquely tied to a device unless you spoof it: www.theregister.com/2011/04/22/google_android_privacy_concerns/
@@fasterthanlime Oh wow i would not have thought of someone actually gathering all the necessary data for that.. but of course its google again... Thanks for the info!
Started learning about how the internet works really enjoying myself don't know here to get more in-depth resources would appreciate any recommendations
i came here thinking i was finally going to understand how to do internet stuff. now i understand that what i actually don't understand is ipv4. nothing changed :c
I don't get NAT hole punching. The hole has been punched for (intermediary_server_, port). Then how can I connect to (friend_ip, port), unless it's the case that NAT only does translation individually from source -> destination and src_port -> dest_port?
I think the reason it works is because the router only needs to remember the port and which local address it’s meant for, and not the source IP. More info here: en.m.wikipedia.org/wiki/Hole_punching_(networking)
@@fasterthanlimeAnd why it doesn't always work - some NAT boxes remember all 5 numbers (protocol, source IP, destination IP, source port and destination port)

In the beginning IPV4, NAT, and BGP were created.
