[afripv6-discuss] Re: [ppml] PI addressing in IPv6 advances in ARIN

Fri Apr 14 14:22:40 SAST 2006

Hi all,

My first idea was submitting a PI IPv6 policy proposal next Monday to RIPE
and the rest of the regions, trying to get a consensus for a "global" policy
on this, but as this thread is being followed up in several mail exploders,
to avoid a long cross-posting, I think it will be better to start some
discussion already in a mailing list which is global, and actually I think
we have the right one ... global-v6 at lists.apnic.net

So, if you aren't subscribed in the global-v6 at lists.apnic.net, and you're
interested in this thread, please subscribe at
http://mailman.apnic.net/mailman/listinfo/global-v6

If you're late because the Eastern, the archives are also available at
http://www.apnic.net/mailing-lists/global-v6/

Regards,
Jordi
