NAME

       dnsviz - issue and assess diagnostic DNS queries

SYNOPSIS

       dnsviz command [ options ]

       dnsviz help [ command ]

DESCRIPTION

       dnsviz is a tool for assessing the health of DNS deployments by issuing diagnostic queries, assessing the
       responses,  and outputting the results in one of several formats.  The assessment may be directed towards
       recursive or authoritative DNS servers, and the output may  be  textual,  graphical,  or  serialized  for
       programmatic review.

       dnsviz  is  invoked by specifying one of its commands as the first argument on the command line, followed
       by arguments specific to that command.  If the first argument is "help", then the usage  of  the  command
       specified  by  the second argument is displayed.  If no second argument is provided, then a general usage
       message is given.
