Sorry, I should have clarified. It's something I haulled off of an ISP discussion list and it appears that some of RIPE's activities may be butting heads with Sprint's route filtering policies. Specifically, RIPE is charging a fee to ISP's to get large blocks of IP addresses to allocate to their customers and yet these blocks are smaller than what Sprint will route.
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 - - - - - - - - - - - - - - - - -
