Commencing 1 January 2007, APNIC will process applications that
specifically request four-byte only AS numbers and assign such AS
numbers as requested by the applicant. In the absence of any
specific request for a four-byte only AS number, a two-byte only
AS number will be assigned.

distinction between two-byte only AS numbers and four-byte only AS
numbers, and will operate AS number assignments from an
undifferentiated four-byte AS number pool.
