Actually, the 100% sure way to know that your caching name server is
working is to run something like "tcpdump" or "ethereal" and capture
only packets for port 53.

When you do a "host" for a known non-cached host you'll see the query
going out.  The second time you do the "host" you should not see a query
going out.
