15. Consensus reached at APNIC 55
• prop-147: Historical Resources Management
– https://www.apnic.net/community/policy/proposals/prop-147/
– Proposed text
• 4.3. Claiming and re-delegating historical resources
– Historical resources Historical resources that are no longer published in the APNIC
Whois Database and are placed in reserved status because of EC resolution 2021-09
of 22 February 2021 can be claimed by the custodians within 12 months of the date
they were marked as reserved
– After 12 months, these resources will be placed in the free pool for re-delegation
– Any historical resources marked as reserved and/or reclaimed by APNIC due to
account closures will lose their “historical” status and become “current” resources for
re-delegation

16. Referral application
• If needing just a small amount of IPv4 addresses for your corporate
customer, consider signing them up as an APNIC member
– Get up to 512 addresses (/23) from last block
• Can grow network and customer base without depleting your IPv4
address pool
• As an existing member have knowledge of policies and procedures
• Any queries contact your friendly APNIC Helpdesk!
