Taking a look at these they appear to be customers. So it could be that these are prefixes that do not belong to KPN but are advertised by KPN themselves (or rather, with KPN as the origin) probably because the customer in question does not have an ASN (or at least a non-private ASN) So its entirely possible this could be a leak of a default from a private ASN customer that KPN carried in their backbone. Of course, since they are providing RV a full feed, not the same as they would to their peers, this should not be a problem for anybody else except KPN (and their customer). The sensible thing to have done would be to have informed KPN privately. Dave.

It looks like they give a full view to the R-V project's router. I don't think this is special in any way whatsoever. If you want to peer with KPN, you should join an IXP they maintain a presence at. (In fact, I suspect that you already peer with them.) -- Niels.

Chris, I'd rather say one should be setting up a normal 'full feed' to routeviews as customers would get it. My view of it at least. So the question is whether this network in question is sending an absoluted unfiltered feed to rv (it seems so, look at all the routes longer than a /24 for example). Now the second question is if that is a special config or default to more than just route-views. To know that find one of the longer prefixes and see if you see it from anyone else on route-views. Go and see. Alexander, not happy

It is not proof. No one said it was. And no one said you said it was. :) That said, I would be grateful if someone showed me I screwed up too - in private. In public, I'm not so sure. Especially if someone only -thought- I screwed up. One could argue that it is difficult to reach the proper people privately (although "noc@" might be a start, or iNOC-DBA, or ...). One could also argue that public notification is better than no notification. But then one would might want to mention that private channels had been exhausted in one's public notification. Anyway, this "one" is sorry if that "one" thought one was being curmudgeonly. :) -- TTFN, patrick
