How is answering any of these questions going to help us? "Oh, NATed
traffic is 7% and not 5%! You are right we should have site local
addresses then!"
But if the number were 50% or higher, I'd think that would have some bearing
on things. If nothing else, it should convince the anti-NAT crowd to work
harder at finding other solutions.
- If we allow people to register non-routable globally unique addresses
for private use, eventually some of this address space will leak out
into the global routing table. In IPv4, filtering private address
ranges and long prefixes is well-established and if and when this
fails, the consequences are negligible.
Without an explicit directive from the IETF (a la RFC2050), the RIRs will
not do this. In words attributed to an ARIN staffer, "We only register
addresses for the Internet, not private networks."
