17 Aug '11

Monday morning at the RIPE 62 meeting, from 9:00 to 12:30, an RPKI workshop will be organized by Randy Bush, Sandy Murphy, and Michael Elkins. For time and place, see meeting plan http://ripe62.ripe.net/programme/meeting-plan. Short description of workshop: The RPKI is a system under development in the IETF that provides a secure method for network operators to attest to the network addresses they hold. Attendees at this workshop will have the opportunity to try out the existing open source implementation for producing RPKI certificates and ROAs with their own resources and experience resource requests, sub-allocations, ROA creation, etc. Attendees will also have the opportunity to experiment with use of RPKI data they have created on a real router and see the impact on routing of use of the RPKI. Attendees who want to participate fully should bring a laptop on which to run the software, either natively or in a virtual machine (OSX, BSD, Linux). No registration is required. Best, -- Benno -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

Hi, In the RIPE region, the following networks are using unallocated 32bit-AS numbers. And it seems they similarly mistook their AS numbers. Are there any products/documents that caused this? 196882(asplain) --mistook--> 196.882(asdot) == 12845938(asplain) - prefix - origin AS (asdot) - origin AS routing table route object in RIPE DB 193.104.235.0/24 12845938 (196.882) 196882 109.233.96.0/21 12845948 (196.892) 196892 195.250.24.0/22 12845948 (196.892) 196892 91.225.224.0/22 12911193 (197.601) 197601 188.191.96.0/20 12911193 (197.601) 197601 - http://www.iana.org/assignments/as-numbers/as-numbers.xml > 394240-4294967294 Unallocated ----- Matsuzaki Yoshinobu <maz(a)iij.ad.jp> - IIJ/AS2497 INOC-DBA: 2497*629
