updating bogon filters for 83/8 and 84/8
hello, On November 15th 2003, IANA allocated 83/8 and 84/8 to RIPE. RIPE has started allocating prefixes from these blocks to LIRs around Europe. We received 83.116.0.0/14 and have started connecting domestic users with these IP addresses. Unfortunately, quite a few ISPs and corporates out there, have not yet updated their bogon filters to allow for these ranges to pass. These are including sites like cnn.com, yahoo.com and excite.com. I'd like to ask everyone to doublecheck whether you are currently allowing these addresses to pass your prefix filters and that you're no longer nullrouting them... Many thanks, Frans -- Quanza Engineering B.V. Elandsstraat 44 Frans ter Borg 1016 SG Amsterdam E: frans@quanza.net www.quanza.net
Hi, NANOGers. ] Unfortunately, quite a few ISPs and corporates out there, have not yet ] updated their bogon filters to allow for these ranges to pass. These are ] including sites like cnn.com, yahoo.com and excite.com. Spread the word! These filters are _easy_ to update. Heck, in one case you don't have to make any changes at all! Please visit the Bogon route-server project page: <http://www.cymru.com/BGP/bogon-rs.html> We provide the bogons in a wide variety of formats, all listed and detailed here: <http://www.cymru.com/Bogons/index.html> If folks require assistance with the modification and testing of filters, please don't hesitate to ping on us! Thanks, Rob, for Team Cymru. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty);

Don't forget about the other half of the problem. ISPs need to verify the network announcements by their downstream BGP networks. Eventually most of the current "bogons" will be assigned, and bogon filters will continue to be less and less useful. On the other hand, positive verification will continue to improve the stability of the network.
