[address-policy-wg] Re: [ppml] article about IPv6 vs firewalls vs NAT in arstechnica (seen on slashdot)

I don't understand your point about why ULA need to be registered if
its not going to be globally routed. Also PI is not the same as ULA -
PI do come from RIRs and in IPv6 there was no way to get PI (except
in a few special cases) until recent ARIN's micro-allocation policy.
