Final phase of four-byte AS number policy now active
_______________________________________________________________________
As of 1 January 2010, APNIC no longer makes a distinction between
four-byte only and two-byte only Autonomous System (AS) numbers.
Instead, all AS numbers are now considered to be four-byte AS numbers.
This change marks the final phase of the transition to four-byte AS
numbers. For more information on the implementation phases of the
four-byte AS number policy, please see "Policies for Autonomous System
number management in the Asia Pacific region" section 6.3, "Timetable
for moving from two-byte only AS numbers to four-byte AS numbers":
http://www.apnic.net/policy/asn-policy.html#6.3

affect your network, see:
