Dear colleagues

From 1 January 2006, APNIC will begin processing requests for four-byte

AS numbers.

APNIC received the following four-byte AS number block from IANA in November 2006 and will begin making assignments from this range after 1 January 2007:

2.0 - 2.1023

AS number syntax in the APNIC Whois Database will be extended to accommodate four-byte AS numbers. This affects all whois database object types that refer to AS numbers. These changes may affect any automated tools you use to interact with the database.

Please note that syntax for two-byte AS numbers will remain unchanged.

For more information on the implementation of the four-byte AS number policy proposal, including a full list of affected whois object types, please see:

Regards
