Maybe it's just me, but isn't there something odd about a DNS query
coming back with 78 entries for the same host? It sends back an UDP
packet that gets truncated and the DNS resolver reverts to TCP to get
the full list.
It seems to cause problems with Windows clients and/or Windows DNS
servers. Seems like overkill.
Here is a dig on www.neopets.com:
;; Truncated, retrying in TCP mode.
