If ARIN policed their IPv4 space more carefully they wouldn't have as many issues with IP space ....

You can have multiple fixed IP addresses on IPv6, so that at least is an advantage, whereas many ISPs typically can only provide one under IPv4.

Hello Michelle,

Your one sentence contains two major false premises:

1. ARIN has no "policing" function. This is not in their charter. The RIRs provide uniqueness in IP registration. While they do promote conservation in their poicies, this is not the overriding goal.

2. they don't really have "issues" with their IP space. They have lots of addresses to allocate still. IPv4 is a much more finite address space then IPv6. It will run out, the only question is when. The pre-cursors to the RIRs (IANA/InterNic) gave out IP blocks in a classful (with hindsight we say wasteful) way. Even if these large blocks had not been given out, that means just a few more years until IPv4 exhaustion.

Hello Michelle,

Please forgive my ignorance, but would Miredo solve an IPv6 request to an IPv4 host? It would seem your 'tunneling' notion would be workable for 'known' IPv6 host to 'known' IPv6 host connectivity - possibly a unique IPv6 only DNS table or some such?
