@scanlime awhile ago you had posted a paper describing variable length network addresses in ipv4 (or earlier), where each 'program' on a computer would get an address and then a router to a subnet would just be a different program, and then this evolved over time to port numbers identifying programs and a fixed address size.
Do you still have a link to that, or any search terms that would help me find it? Thanks.

... and I am sure it continues as the evolution of the protocol got to v4)
