       Random thought: why are IPv4 addresses "only" 32 bits? Why did the people who designed it think that 4×10⁹ addresses were enough?So I did a bit of historical diggingIPv4 was activated on 1983-01-01A few months before, in March 1982, there were about 240 hosts and about 7000 people in the whole world, that you could address via the ARPANET and other networks.Two hundred and forty.No wonder 32 bits seemed enough! It must have felt like an exhuberant level of future proofing!

       @dakkar@s.thenautilus.net "This exorbitantly large number that utilises the maximum amount of bits in 1 unit (32 bit processors lol) sounds like a good enough number, we definitely will never need more" - Some engineer somewhere, at some pointFamous last words ​:kekw:​Also by the time IPv4 is actually obsoleted, we'll be an interplanetary species 130 planet colonizations away from needing an IPv8, because v6 will be too little to support all the 340+ undecillion devices in our 326 terraformed planets with an average of 6B inhabitants per planet lol

       @dakkar@s.thenautilus.net Let me tell you about the early proto net and the early days of the internet.1st, we all used our real names (no anonymous screen names).  2nd, access was free (you didn't need to pay to get online, just dial the access number).  3rd, there were no photos, videos, as it was all text. 4th, The 1st art on the internet was text art. 5th, there were technically no ads, though most websites serves as government and business listings (address, phone, hours of operation, basic summary). 6th, there were no dot coms, you had to remember IPs like you did phone numbers.

       @Linux@kitty.social I was online in the very early '90s, I remember most of that!Although… Liz Feinler had been maintaining the host name list since the mid-'70s, and the DNS was mostly running in 1985.

       @cody@catboy.baby related: https://github.com/torvalds/linux/blob/master/net/ipv4/tcp_timer.c#L625-L639Note that 120 sec is defined in the protocol as the maximum possible RTT.  I guess we'll have to use something other than TCP to talk to the University of Mars.

       @dakkar@s.thenautilus.net I'd suggest ITCP, and ISTCP for extra-solar system communications, ITCP (Transmission Control Transport), ISTCP (InterSystem Transmission Control Transport) ​:3:​OOOOooOoooR we can just wait until we find some quantum bs that allows us to mutate the state of bits instantaneously using quantum entanglement I guess...
