It specifies whether the Authoritative Answer flag in the answer is set.

My first guess at the reason for the difference was that 199.191.128.106
was not configured as a slave for hpcwatch.com.  But both those servers are
slaves for their corresponding domains, so that doesn't seem to be it.  Now
I suspect that the difference may be related to the versions of BIND
they're each running.
