ahhhhh... ok... i hadn't yet had a chance to go looking in that unit... trying 
to first complete the email wading for the day ;)

FWIW: if i were to just be hunting and digging, the name of the unit would throw 
me off because it seems to indicate network database functions whereas i 
wouldn't think that DNS lookups and the like are database oriented... not like 
SQL stuff... but i guess the DNS is a form of database, isn't it ;)
