New on RIPE Labs - How many RIPE NCC ASN holders use RIPE Routing Registry?
by Mirjam Kuehne 28 Jan '11

28 Jan '11

[apologies for duplicates] Dear colleagues, It is often claimed that the Internet Routing Registry is not accurate and complete enough. Is this really the case? In a new article on RIPE Labs, we look at how many organisations that receive an Autonomous System Number from the RIPE NCC use the RIPE Routing Registry: https://labs.ripe.net/Members/mirjam/interesting-graph-how-complete-is-the-… The next step will be to find out how accurate this information is. Kind Regards, Mirjam Kuehne RIPE NCC

19 Jan '11

Folks, With very many thanks to the NCC for producing them promptly, and very many apologies from me for sitting on them for so long, the draft minutes from our meeting in Rome are here: http://www.ripe.net/ripe/wg/routing/r61-minutes.html If you have any comments, please let Joao and myself know with an email to: <routing-wg-chairs(a)ripe.net> Thanks, and of course it won't do any harm to start thinking about what you want to discuss in Amsterdam in the first week of May. :) All the best, Rob
