6. Conclusions
• An APNIC account holder (including NIR members) can
receive up to a /22 from the final /8 pool (103/8)
• In addition, you can receive up to a /22 from the recovered
pool (non-103/8) as long as the recovered address pool has
enough IPv4 addresses
• Please do not forget about IPv6. What’s your plan ?
