DESCRIPTION

14       dnsviz is a tool for assessing the health of DNS deployments by issuing
15       diagnostic queries, assessing the responses, and outputting the results
16       in  one of several formats.  The assessment may be directed towards re‐
17       cursive or authoritative DNS servers, and the output  may  be  textual,
18       graphical, or serialized for programmatic review.
19
20       dnsviz  is invoked by specifying one of its commands as the first argu‐
21       ment on the command line, followed by arguments specific to  that  com‐
22       mand.   If  the first argument is "help", then the usage of the command
23       specified by the second argument is displayed.  If no  second  argument
24       is provided, then a general usage message is given.
