APNIC IPv6 pools and
delegation practice
Guangliang Pan

APNIC IPv6 delegation history
• 1999-07-01 IANA made its first IPv6 allocation 2001:0200::/23 to
APNIC
• 1999-08-13 APNIC made its first IPv6 allocation 2001:200::/35 to
WIDE project Japan
• 1999-07-01 to 2006-10-2, 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
• 2006-10-03 IANA allocated 2400:0000::/12 to APNIC
• 2006-10-10 APNIC made the last /32 sequence allocation
• 2006-10-20 APNIC started the sparse allocations from the
2400:0000::/12 pool

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 2006. It is part of the 2400::/12

2002-05-02 2001:0C00::/23 54 *
2003-01-01 2001:0E00::/23 61 *
2004-06-11 2001:4400::/23 41 *
2006-01-19 2404:0000::/23 ** 26 *

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)

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

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
