It does make a lot of sense for NANOG (perhaps jointly with RIPE and
other NOGs) to organize monthly IPv6 days with a theme or focus for
each month. If you have a focus, then you can recruit a lot of IPv6
test
le who carry DOD
traffic could borrow the APNIC block.
This actually reduces the pressure on the IPv4 address supply without
expensive carrier grade NAT services and makes the transition to IPv6
less turbulent.
