Global IPv6 policy question

[David Conrad]

Hi,

IANA has been asked to provide input to ICANN's board on the RIR- 
consensus global IPv6 allocation policy (see http://www.icann.org/ 
announcements/announcement-14jul06.htm for details), so I'm looking  
to understand what folks in the v6 operational community think.

One question would be the choice of /12 as the minimum allocation  
size for IANA to allocate IPv6 addresses to the RIRs.  Do folks  
consider this

a) just right
b) too little
c) too much
d) why are you annoying me with this?

Another question: does your answer change with changes to either a  
more conservative HD ratio or a longer minimum end user prefix length?

Thanks!

Rgds,
