[routing-wg]Assignments of 32 bit AS Numbers

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-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 at ripe.net>.

Kind Regards,

The RIPE NCC
