RFC 1918, section 3:
"[...]Because private addresses have no global meaning, routing
information
about private networks shall not be propagated on inter-enterprise
links, *and packets with private source or destination addresses
should not be forwarded across such links.*"
...But that's not what's happening in the case of the traceroute which
started this discussion. The only reason we're seeing those private
addresses is because we're basically snooping around in someone else's
network. RFC 1918 is still being upheld - privately-addressed traffic is
not being forwarded over inter-enterprise links.
The difference is this: "information about private networks shall not be
*propogated*"...meaning my routers must not actively advertise my private
networks to external ASes. Well, okay - the ISP isn't doing that. But when
we trace through a network using private addresses, we will see them - we're
snooping around, but the routers aren't actively propogating those private
numbers.
I'm excited about IPv6...but if we can make v4 last a little while longer,
hey, let's do it. ;-)
