RIS to be modified to support 4-byte ASNs

[Apologies for duplicates]

Dear Colleagues,

>From 1 January 2007, the RIPE NCC has been assigning 4-byte Autonomous
System Numbers (ASNs) to members. To support this, the Routing
Information Service (RIS) will soon be modified so that RIS output can
include 4-byte ASNs. Any tools you use that parse RIS output should
therefore be updated to allow this.

Raw data dumps from the RIS will also be affected and you should ensure
any tools that read it are capable of handling the new format.

The exact date when 4-byte ASNs will start appearing in the RIS is not
yet known, as software is being still tested and modified. The RIPE NCC
will post a notification three business days in advance of any
changes being implemented.

Details of the changes to the RIS can be found at:

If you have any questions, please send an e-mail to ris at ripe.net.

Regards,

Erik Romijn
Information Services Department
