How big would a network need to get, in order to come close to exhausing RFC1918 address space? There are a total of 17,891,328 IP addresses between the 10/8 prefix, 172.16/12 space and 192.168/16 space. If one was to allocate 10 addresses to each host, that means it would require 1,789,132 hosts to exhaust the space.
See 30 minute mark of https://youtu.be/ARlBHmPy7Zc?t=1787. We talked about this in a NANOG88 presentation too but had a bigger timeslot to talk at AusNOG so we said a bit more about it.
