I oppose 125

I know I'm late on this thread, but you expect ARIN to actually monitor 
A/AAAA records and somehow figure out abuse? Are we to give ARIN access 
to every box so they can confirm that there is a v6 address on the box 
as well? What about the millions of boxes which don't use A/AAAA records 
or need them?

125 proposes something that ARIN has no way of enforcing (which is 
probably one reason it was tossed). In addition, it's overly restrictive 
for those who do follow the rules.

There are still plenty of interfaces that have no need, nor can support, 
IPv6. Perhaps it's changed, but MPLS wasn't working with v6, management 
of CPE sure as heck doesn't need v6 in the short term.

Finally, dual-stack is not the only migration technology. For ARIN to 
enforce one migration method over another will only hinder v6 migration.
