1. APNIC IPv6 pools and delegation practice
Guangliang Pan

2. APNIC IPv6 delegation history
IANA made its first IPv6 allocation 2001:0200::/23 to APNIC
APNIC made its first IPv6 allocation 2001:200::/35 to WIDE project Japan
to , IANA allocations were based on /23 size block. RIRs started with a /35 minimum allocation (later change to /32 from 1 July 2002) from a reserved /29 in sequence allocation
IANA allocated 2400:0000::/12 to APNIC
APNIC made the last /32 sequence allocation
APNIC started the sparse allocations from the 2400:0000::/12 pool

3. APNIC IPv6 sequence allocation pools
Normal /32 allocations were made from /23 pools before Oct 2006, each /23 can have up to 64 allocations and each allocation was reserved up to /29.
* Some allocations are larger than /29 in those ranges
** 2404:0000::/23 received on 19 Jan It is part of the 2400::/12

4. APNIC IPv6 sparse allocation pools
In Oct 2006, sparse allocation started. Normal /32 allocations are made from
2400::/13 (allocations can grow up to /25 at this stage)
Very large allocations are made from
2408::/13 (allocations can grow up to /17 at this stage)

5. Additional pools
APNIC received a few allocations that are larger than /23 from IANA to meet some large requests in our region before 2006.
2001:8000::/19
2001:A000::/20
2001:B000::/20

6. Special Ranges APNIC reserved some ranges for special purposes.
2001:0DC0::/27 Used for Critical Infrastructure
2001:0DE8::/29 Used for Internet Exchange Points (IXPs)
2001:0DF0::/29 Used for Portable assignments
2001:0DE0::/29 Used for experimental purposes
2001:0DB8::/32 Used for documentation purposes
2001:07FA::/32 Used for IXP assignments before 2007
