Specifically RIPE are allocating /19s as their default allocation window to local-IRs. They don't charge per block but they charge a yearly fee for being a local-IR. Sprint in its wisdom is filtering those in 195/8 (great theory, but a bit problematic in practice when it can't agree with one of the larger registries on what size to filter) with the result there are now likely to be 50% more adverts (i.e. 2x/19 and an additional /18 - /19 still necessary to get ANS to work as you can't put a /18 route object in the database). > I was kind of hoping that someone would pipe up and say that the > operations folks and the IP registres are now working closer and > coordinating their activities. Am I dreaming?.... AFAIK Yes. But it would be great if not (I wasn't at NANOG so missed the announcement). Alex Bligh Xara Networks - - - - - - - - - - - - - - - - -
