Starting to digress here for a minute...

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.

Not very long ago I worked for a well-known e-commerce platform where we nearly
ran out of RFC1918 space. We seriously considered using what was then
un-advertised DOD space to supplement RFC1918 space inside our data centers.

Perhaps AliExpress did get to that level of desperateness?
