ARIN-prop-150 Reclamation Hold

Proposal Originator: Matthew Kaufman

Proposal Version: 1

Date: 13 May 2011

Proposal type: new

Policy term: permanent

Policy statement:

Add a new section to the NRPM:
"All resources reclaimed by ARIN shall not be returned to the free pool
or otherwise reassigned to any entity than the original registrant for a
period of 36 months."

As the pressures on the system become greater with IPv4 runout, there
will be more call for ARIN to reclaim address space. When addresses that
are reclaimed are reused too soon, a variety of undesirable outcomes may
result. This provides sufficient time for the resources to go unused
prior to reassignment and/or to be re-justified by the original
registrant, or returned to the proper holder in the case of hijackings.
This policy could be restricted to IPv4 space, but it may be useful for
AS numbers and has no major impact on IPv6 space (due to the large free
pool), so it might as well apply to all.

Timetable for implementation: immediate
