Yeah this is pretty much what I'm doing. ULA for stable, internal addresses
that I can put into the (internal) DNS: ISP prefixes for global routing.
Renumbering is hard.

All of the objections I've seen to ULA are actually objections to (IPv6)
NAT, which is why I was confused.

(As it turns out my ISP prefix has been static for years, but I'm too lazy
to undo all of the work...)
