Update to RIS raw data format for 4-byte ASNs

Dear Colleagues, This is an update concerning 4-byte Autonomous System Numbers (ASNs). An IETF draft has been released describing a new version of the MRT format, used for RIS raw data. We have published a new version of libbgpdump to support this, which can be downloaded from: http://www.ris.ripe.net/source/ There is at this stage no set date on which 4-byte ASNs will appear in the RIS. The current raw data does not use the new format. Details of the changes to RIS for 4-byte ASNs, including more information on the new raw data format, 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>.
