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:

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?
