NAT for an ISP

Wed Jun 4 20:56:15 UTC 2003

ISPs that provide RFC1918 space should also provide recursive DNS services
that would stop all RFC1918 in-addrs before hitting root-servers and
guidance to their users so they do the same on their servers if they don't
forward requests to the ISP recursive resolver.
