It actually predates that even - rfc790 defines it as AMPRNET as part of ARPANET in 1981.

I spent a bit of time tonight trying to find the old pre-ARIN iana/isif Usenet group and failed. I'd imagine a list that predates ARIN would have some interesting history around this. ARIN's history has the net block assigned by IANA in 1992-07, but their records only show it in existence from 1996.

Additionally, ARDC (the nonprofit that currently owns 44/8) was only registered as such in 2011.

I'll keep looking when I have time.

Great work on this! NANOG has a good thread going (as one can imagine...). Good post here: https://mailman.nanog.org/pipermail/nanog/2019-July/102131.h...
