RFC1597 addresses are those addresses whose routes do not have to be
accepted from anything outside of the "local" scope.  If you consider
"local" to be your site, then great.  If I consider "local" to be my
network infrastructure (excluding your renegade site :-) that's also fine.

Just as a site's network is "private" (and hence can use RFC1597 addresses),
a provider's infrastructure is also "private" for those packets which do
not leave their network.
