These guidelines are intended to complement the policy on the recovery of historical address space described in 4.2.1. Recovery of unused historical address space of APNIC Internet Number Resource Policies. They are intended to guide networks holding historical address space.
Historical address space that has been globally routed at any time since 1 January 1998 is not affected by this policy.
2. Address Recovery Process
The following steps will take place:
APNIC identifies historical address space that is not currently being globally routed
APNIC will check the list of historical address ranges against historical routing data available from a prefix announcement database. If addresses from a historical address range have not been routed at all since 1 January 1998, APNIC will begin the process to recover the resources.
APNIC notifies the network contacts of the intent to reclaim unrouted resources
APNIC will use the contact details of the admin-c and tech-c for the address range to notify the network of its intent to recover resources.
The network responsible for the unrouted resources can choose to return the resources to APNIC or maintain custody
If a network is contacted by APNIC and is notified of APNIC’s intention to recover the unrouted resources, the network can choose to:
If there is no response from a network, APNIC will keep trying to contact the network for one year before reclaiming the resources
At the end of one year, if there is still no response from the network, the address range will be reclaimed.
Reclaimed resources will be returned to the free pool for redistribution in the future
The origin of the historical resource will affect what happens to the reclaimed resource:
