Ok, we set up an access list for the whole class of IP's that we are
having problems with since whoever is doing this keeps dialing up and
getting a new IP. Since setting up the access list we saw over 7000
attempts to query our DNS server in the first 20 minutes:
Extended IP access list 112
deny udp 62.226.0.0 0.0.255.255 any (7194 matches)
Why on earth would anyone do this?
They appear to be querying every single reverse record on the internet
one by one.
