There is a bug in all current PowerDNS recursor versions where it neglects to erradicate the contents of the hints file from its cache. This means that both the old and the new IP address of l.root-servers.net will continue to be used, until the hints file expires from the cache, which is sadly only after 40 days of uptime. I apologise for this bug, and promise that a fixed PowerDNS recursor will be released swiftly. However, I don't think 40% of the world is running the PowerDNS Recursor, so there must be something else to blame, as well.

Why old root server IP addresses recieve so much traffic is a great mystery and has been for several years. We addressed this in 2004 in the Life and Times of J-root presentation for NANOG 32: http://www.nanog.org/mtg-0410/pdf/kosters.pdf Note that at the time, I fingerprinted the responsive queriers and many were late-model BIND, all of which are known to prime. As I write this, J root's old IP address is receiving 1000 queries per second and that's over five years after we changed its address. Perhaps this is some sort of DNS equivlanet to cosmic background radiation, dating back the beginning of the Internet?

Matt and perhaps more interesting, the old address for B showed a tapering off of traffic and then an INCREASE last year. Old L and J got their numbers less than a decade ago. ... so i would not go back as far as the begining of the Internet. Old B has been around for quite a while longer. --bill ___ DNSOP mailing list DNSOP@ietf.org https://www1.ietf.org/mailman/listinfo/dnsop

The increase in traffic might easily be due to more favourable connectivity to 'B', which would lead many resolver implementations to shift more queries to it.

Bert old B topolgy didnt change... :) Admittedly, you have a far better view of the internet than I do :-) - But I'm not ruling out changes *other* people made to their networks. Also, perhaps the other roots just became less attractive.
