I think I see the confusion here - the OP is seeing those two log entries 
as being two distinct queries, but what it sounds like you're saying, 
Mark, is that it is in fact two log entries for the same query, one for 
the actual query itself, and the second for the internal lookup following 
the CNAME.

Neil, can you check the logs of netmgrts.cso.niu.edu for a recent query 
for huskiesden.niu.edu from 63.208.196.3?  Do you see both entries? 
Because I ran tcpdump as I ran the query, and I definitely only sent one 
query to that server, so if you see both entries, that confirms what I 
think Mark is saying, and hopefully solves the mystery.
