the protocol name should be "TCP+IP", because "TCP/IP" suggests these are independent layers, which in fact isn't true

@amiloradovsky yes, they are. You can use IP with UDP!

@newt you can't use IP alone with a custom protocol instead of TCP or UDP

@amiloradovsky sure you can! IP-IP tunnels are a thing. Unless NAT or some other kind of firewall fuckery is involved, you can put literally anything on top of IP and it'll likely work. Most routers don't really care.

@amiloradovsky I think it's TCP *over* IP, not 'in addition to'.and they are separate layers.

@joey "knowing" the OSI model beyond just distinguishing layer 1, 2, and 3 is a strong indication of somebody I don't want to talk to -- being sure of something inherently vague is a bad trait(same for "knowing" e.g. software design patterns and other bullshit)the slash symbol is overloaded, just a few meanings- one thing on top of another (over)- alternatives (or/xor)- path separator (as in unices)- field separator (as in dates)- division (fraction, ratio)- quotient/factor structures (group by normal subgroup, ring by ideal in it, set partitioning into cosets by equivalence relation, etc.)

@ic3l9 @marshray @amiloradovsky hey! Everyone has kinks! Imagine spending your young years designing network protocols among sweaty fat nerds.

@amiloradovsky @newt Here are 144 examples of doing exactly that: https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

@marshray @amiloradovsky i love how many entries on that list are basically "Intenert Derp Herp Protocol" and some dude's email as a reference, because the lad allocated this number for himself some time in 1992.

@marshray @newt OK, now I want to try and send IP packets across the world with garbage payload and random protocol numbers only maybe different from 6 and 17, then gather some statistics on how they'll be delivered (how quick if at all)

@newt @amiloradovsky Yeah, that’d be some really useful research.Over the internet backbone carriers and through various firewalls and VPN providers. It’d be good to get stats on how IP options flags and source address spoofing are treated while you’re at it.Reminds me a bit of the kind of stuff the https://explorer.ooni.org/ project does.
