We can also say "This space is quite possibly used on the inside
of customer-managed devices and thus might create routing system
confusion. As with all use of non-unique address space, the responsibility
falls on the communicating parties to coordinate their address block
utilisation so as to avoid damaging amounts of ambiguity."
I did 1918 coordination in joint venture networks 12 years ago, and felt
the pain. If I did, then, being the wet-behind-the-ears can-do optimist
that I was, why is it that nobody more sane in the industry realised it?
I find it repulsive to excessively pamper the late-comers to something
that we've KNOWN was going to happen for 15 years.
draft-weil-shared-transition-space-request should be rewritten to offer,
say, 172.28/16, as "Mostly used between CPE and CGN" and we all should
move on to deploying IPv6 and get the ops warts out of it.
