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 ;)
