Avoiding a Bogus Name Server

In your term as name server administrator, 
you might find some remote name server that responds with bad information --
old, incorrect, badly formatted, or even deliberately deceptive. 
You can attempt to find an administrator to fix the problem.
Or you can save yourself some grief and configure your name server not to ask questions of this server,
which is possible with BIND 4.9, BIND 8, and BIND 9.1.0 and later.
