[arin-ppml] IPv6 policy: reservations?

[William Herrin]

Howdy,

I didn't see any feedback on the draft policy rewriting section 6.5,
so I want to step back and solicit your opinions on what ARIN's IPv6
policies should become. I'm going to ask some questions and break them
into separate message threads so that they can be followed separately
according to your interest.


The question for this thread is: Should ARIN continue to reserve a
larger IPv6 block than allocated to allow for expansion?

The policy currently calls for reserving up to the next nibble
boundary in allocations so that registrants can expand their holdings
by changing the netmask up to 16x the initial number of addresses.
This way you can get the addresses you need now at the fee you're
willing to pay now but still grow significantly later on before
needing a discontiguous allocation which would require you consume
another BGP slot.

Is this the right amount of reservation? Should there be more? None?
Your views are respectfully requested.

Regards,
Bill Herrin
