In this case that's not a good idea. It's almost certain that knoppix
is being resolved by the DSL modem and +trace will bypass that and do
all the recursive queries to ask the 2wire.com authorities for the name.
That will fail and just confuse the situation.
But generally +trace is a good way to see on your machine the kinds of
queries that DNS makes for you.
