[arin-discuss] Trying to Understand IPV6

[Owen DeLong]

Tom,

If you know you have 115k customers, you should request more
than a /32 to begin with. Probably something approaching a 30
or a /29 under current policy. I am soon going to be drafting a  policy
proposal that supports the notion of rounding up to nibble boundaries
in order to provide better guidance to ISPs on right-sizing their requests
and also to provide better human factors engineering in the address
space overall.
