_______________________________________________________________________ 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 To learn more about how the transition to four-byte AS numbers may affect your network, see: http://icons.apnic.net/asn If you have any questions or need further assistance, please contact: helpdesk(a)apnic.net _______________________________________________________________________ APNIC Secretariat Asia Pacific Network Information Centre (APNIC) Tel: +61-7-3858-3100 PO Box 2131 Milton, QLD 4064 Australia Fax: +61-7-3858-3199 Level 1, 33 Park Road, Milton, QLD http://www.apnic.net
