## DESCRIPTION

Like DNS, but uses Net::DNS and Time::HiRes instead of dig. This probe does \*not\* retry the request three times before it is considerd "lost", like dig and other resolver do by default. If operating as caching Nameserver, BIND (and maybe others) expect clients to retry the request if the answer is not in the cache. So, ask the nameserver for something that he is authorative for if you want measure the network packet loss correctly.

If you have a really fast network and nameserver, you will notice that this probe reports the query time in microsecond resolution. :-)
