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
[Apologies for duplicates] Dear Colleagues, 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: http://www.ripe.net/projects/ris/docs/asn.html If you have any questions, please send an e-mail to ris@ripe.net.
