Hi,

Back during the IPng ‘discussions', I once said (in support of variable length 
addressing) that there was no fixed amount of address space that address 
allocation policy couldn’t consume.  A case in point...

This seems quite at odds with how Internet routing works.

This is not what IP addresses are for. Overloading universal identification 
onto IP addresses would needlessly complicate address allocation, routing and 
routing software, etc., and consume address space for no useful end, at least 
in terms of use on the Internet.

IP addresses are endpoints of IP communication, not universal identifiers.  
Non-electronic items have no need for IP addresses and could, instead, use any 
of myriad identifier schemes (see 
https://en.wikipedia.org/wiki/Category:Unique_identifiers)
