Dear Colleagues, From 1 January 2007, the RIPE NCC can assign 32-bit Autonomous System Numbers (ASNs). There is more information about this policy in ripe-389: http://www.ripe.net/ripe/docs/ripe-389.html Details of how to request a 32 bit ASN are in ripe-396: http://www.ripe.net/ripe/docs/asnsupport.html ASN32 objects will appear in the RIPE Database from 1 January 2007. Their format is different from the current 16-bit ASNs. The new format is described in these documents: http://www.ietf.org/internet-drafts/draft-michaelson-4byte-as-representation... http://www.ietf.org/internet-drafts/draft-uijterwaal-rpsl-4byteas-ext-01.txt The introduction of 32-bit ASNs may have an effect on tools that query the RIPE Database or those based on RPSL. A test server is available. There is more information at: http://www.ripe.net/news/asn-test-server.html Sites using the RIPE Database software will probably have to upgrade their systems, see: http://www.ripe.net/news/asn-db-update.html For more information, please contact us at <asn32@ripe.net>.
