   I'm not even mad at CGNAT anymore, I'm just really mad at the IPv6 adoption and missing resources around it.

   For most of my friends who did not take the deep dive into computers and especially computer networks, an IP address is four octets containing funny numbers.

   A friend of mine got really confused when I mentioned that there is another IP version: IPv6 (which of course did NOT work for the use case we were trying to achieve: making proprietary software talk with eachother).

     @famfo this is so fucking sad. like ipv6 has been around for almost forever, but in most usecases its still considered second-tier. heck even in the current curriculum of my abitur we still learn mainly classfull!!! ipv4 ("obsolete network addressing architecture used in the Internet from 1981 until the introduction of CIDR in 1993"). how is this possible? im writing my exams in two months and i wont get points if i assume classless networking??

     we're fucking stuck in 1993

     @fossdd @famfo Reminds me of how often people refer to OSI layers… even though OSI was dead on arrival and TCP/IP was the one that actually worked.

     @muxelplexer @famfo @fossdd Except there's no such thing as layer 1/2/…/5/6 on TCP/IP.
     
     You can put whatever you want in-between when it comes to TCP/IP, in any-amount, after all HTTPS didn't need a protocol change for HTTP.
     
     And it's not just in TCP payloads, which layer exactly is PPPoE? :D

     @lanodan @famfo @fossdd but isnt the issue with TCP/IP the combination of OSI layer 1 & 2? Not like anyone will care about OSI layer 5/6 these days either but we've been told thats why both are still around battling around

     @fossdd @famfo You need to be actually somewhat competent to understand IPv6 and it seems many people are so incompetent they go disable IPv6 and use IPv4 only.

     @muxelplexer @famfo @fossdd I do think there's a bit of value in doing the difference between physical and internet, but you don't need OSI for this.
     OSI can be left out with X.25 and the other protocols it had at the time.

     @lanodan @famfo @fossdd generally you can just use either and make the best of both worlds by acknowledging the OSI split between physical/link and the TCP/IP amalgation of application layer - but in terms of naming the layers imo OSI is superior

     Except there’s no such thing as layer 1/2/…/5/6 on TCP/IP. Yeah - they aren’t numbered. There is still Link/Internet/Transport/Application Layers though. Call them what you want but imo that’s a bit pedantic lol.

     Yes - but that only applies from the Transport layer upwards - as it does with OSI. In OSI we just ignore Session/Presentation since they are obsoleted. Once you go downwards you have abstracted a physical electrical connection together with a link-layer MAC connection - which is not beneficial when working on those lower layers.

     PPPoE is encapsulation of Layer 2 frames in Layer 3 packets in OSI terms, which is nothing too mind bending.

     ((sorry if i come off as a bit annoyed but OSI layer model is more than just a reference for programmers and i may have PTSD on the layer systems from Networking classes :p ))

     @muxelplexer @famfo @fossdd And I think trying to wrangle the TCP/IP and somewhat related protocols into OSI layers (be them numbers or names, doesn't matters) is trying to make round pegs fit into a square hole.

     @muxelplexer @famfo @fossdd Not good at pre-RFC history of the internet but as far as I can tell DARPA was even older than that (I know there was UUCP and NCP).
     
     And OSI (which is from ISO) would mean new protocols, and as far I can tell, it failed to actually get deployed outside of labs.
     
     While TCP/IP managed to just encapsulate older protocols (as seen by it supporting the dinosaur that is FTP).

     @lanodan @famfo @fossdd also on a side note: wasn’t it technically the DARPA networking model instead of TCP/IP or do i have brainworms?

     @lanodan @famfo @fossdd i can get that sentinment - it probably feels natural to me since that was how our networking prof got us to layer the networking (coming from a infra/administration background). Ignoring Layer 2 is just not possible when you operate with non-multi-layer switches (i.e. good ol switches)
