RFC1918 equiv

[Richard Draves]

The KAME comment is not correct. The MS stack supports site-local addresses
for hosts & routers, including

draft-ietf-ipngwg-site-prefixes-04.txt
draft-ietf-ipngwg-scoped-routing-03.txt
draft-ietf-ipngwg-scopedaddr-format-02.txt
draft-ietf-ipngwg-scoping-arch-01.txt
