1. AFAIK, it is not "illegal" to number router interfaces out of 1918
space (but you don't want to do that if you need to generate path MTU
2. DNS is escaping packets, not escaping routes = irrelevant
3. Leaking RFC 1918 prefixes in BGP only means that SOME people don't
use good filters SOME of the time (probably all people some of the
time / some people all of the time, but that aside), not that the
state of route filtering is such that internet-wide connectivity can
be had using address space that most people feel should be filtered
