3. Problem statement
From http://www.potaroo.net/tools/ipv4/ as of 11 September 2017
Need a policy to
manage exhaustion
• 103/8 pool will run out soon.

4. Proposed policy solution 1/2
Guidance for 103/8 pool exhaustion:
• The first time an approved request cannot be fulfilled from the 103/8 pool, Final /8
delegations will end.
• APNIC will begin to manage only one (Recovered) IPv4 pool containing any residual
103/8 space and all future returns, including 103/8 returns.
• Each new account holder can receive up to a /21 from the IPv4 Recovered pool.
• Existing account holders who have not yet received the maximum /21 from the two
pools may continue to apply for space from the Recovered pool until they have
received a maximum.
• A waiting list will be created if approved requests cannot be fulfilled. Each new
account holder will be given priority in the waiting list.

6. Advantages / Disadvantages
• Advantages
– Possible to avoid confusion when Final /8 pool will run out
• Disadvantages
– None

7. Impact on APNIC/LIR
• No impact to current resource holders.

8. Questions on sig-policy ML
Q:
After exhaustion, will initial resource requests from new Members be
filled before unmet requests from Members already on the waiting list
prior to exhaustion? Or will this priority only apply to requests submitted
after the exhaustion date?
A:
This prioritization will be applied to requests of members submitted after
the exhaustion date. The waiting list before the exhaustion date
should leave it as is, and add new prioritized requests bottom of the list.

9. Summary
• Proposal for managing Final /8 pool exhaustion
• Managing one IPv4 pool for all IPv4 addresses requests
• Distribute up to /21 to each LIR
