Draft Policy ARIN-2011-6
Returned IPv4 Addresses

Date: 18 April 2011

Policy statement:

4.1.9 Returned IPv4 Addresses

Until a global policy which clearly defines a mechanism for the re-allocation of IPv4 addresses returned to the IANA is adopted by all five regions and implemented at the IANA; all IPv4 addresses returned to, recovered, or revoked by ARIN will be made available for allocation or assignment in the ARIN region as quickly as practicable.


Adopting this proposal will result in the clarification of the status of returned IPv4 addresses. IPv4 address resources should not sit idle due to lack of policy clarity.

Timetable for implementation: Immediately
