Use "dig www.something.com a", where www.something.com is a name that
should be found but fails (e.g. www.yahoo.com). If the result contains
"status: NXDOMAIN", look in the Authority section of the reply. If it
contains NS records for the root domain that aren't like
A.ROOT-SERVERS.NET, or NS records for COM that aren't like
A.GTLD-SERVERS.NET, then your cache has been poisoned.
