IPv4 Address Renumbering for HKIX Public Peering LAN: 12-15 Jun 2015 HKT (Fri-Mon)
Dear HKIX Participants,
This year is the 20th Anniversary of HKIX, which was set up in 1995. HKIX has experienced steady growth during the last 20 years. To cope with the growth, a lot of changes and upgrades had been done already. For the IPv4 address block currently used for HKIX Public Peering LAN (202.40.160/23), we have already used up more than 80%. In order to cope with the continuous growth of HKIX and having learnt from the experience of other IXPs around the world, we have decided to perform IPv4 address renumbering for HKIX Public Peering LAN during 12-15 Jun 2015 HKT. This is the only option for solving the problem while minimizing the impact to the HKIX community.
A NEW IPv4 address block will be used and the network mask of HKIX public peering LAN will be changed from /23 to /21. All HKIX participants will have to re-configure the IPv4 addresses on their routers in order to use the new IPv4 addresses to do peering over HKIX.
During the 4-day migration (12-15 Jun 2015 HKT), HKIX will do parallel-run of both new and old IPv4 address blocks. HKIX new route servers will serve the multilateral peering for new address block while the existing route servers will serve the multilateral peering for old address block. HKIX participants can change their peering IPs at any time during the 4-day migration period and the old HKIX route servers and the old IPv4 address block 202.40.160/23 will cease operations right after completion of the IPv4 address renumbering on 15 Jun 2015 HKT.
Pre-announcement of this migration was made during APRICOT-APAN 2015 held in Fukuoka last week at “Peering Forum (2)” and “Lightning Talks” sessions. Please refer to the following links:
