RIPE 63, Vienna
by Rob Evans 16 Sep '11

16 Sep '11

Hi, Time marches on, and soon enough we will be at yet another RIPE meeting, this time in, according to The Economist, 2011's second most liveable city in the world, Vienna (I don't believe we'll be meeting in Melbourne any time soon, so this will have to do). Registration for the meeting is now open, and can be found along with lots of other lovely information at the meeting website: <http://ripe63.ripe.net/> Our working group is currently scheduled to meet on Wednesday afternoon, but be aware that until the meeting plan is finalised, that could change to any other point between Wednesday and Friday. If you'd like to present something to the working group, please drop Joao and myself a message at <routing-wg-chairs(a)ripe.net>. If you have some plenary content you'd like to present, then we have instigated a programme committee for RIPE 63, you can find the details at the following location: <http://ripe63.ripe.net/programme/submit-a-topic/> See you in Vienna! Rob

Web-based ROA Repository now public
by Alex Band 05 Sep '11

05 Sep '11

[Apologies for duplicate emails] Dear colleagues, The RIPE NCC ROA Repository holds all of the Route Origin Authorisation objects created by the network operators using our Resource Certification service. ROAs state which Autonomous Systems are authorised to originate the prefixes an LIR holds. The repository currently contains over 350 ROAs covering more than 220,000 IPv4 /24 prefixes, which is almost 10% of the IPv4 address space registered in the RIPE region. Details on individual ROAs were only publicly available by running a command line validation tool. We have now made a Web-based ROA Repository available for everyone. It allows you to download and view details of all ROAs and related certificates, AS Numbers and prefixes. Please check out the page here: https://www.ripe.net/certification/repository If you would like to try out the RIPE NCC Resource Certification system, please have a look at this page for the steps to enable it: http://ripe.net/certification/enable.html Don't forget to create your ROAs and make sure they reflect your BGP routing! If you have any questions, please do not hesitate to contact us via certification(a)ripe.net. Kind regards, Alex Band Product Manager RIPE NCC
