NAME

       dns_tree — command-line frontend to dig

SYNOPSIS

       dns_tree [-f]  [-v]  [-d]  [-t TYPE]  [-m MATCH] DNS_domain

DESCRIPTION

       This manual page documents briefly the dns_tree command.

       This  manual  page  was  written for the Debian distribution because the original program does not have a
       manual page.

       dns_tree is a program that works as a front-end to dig.  Given  a  specific  domain  dns_tree  will  make
       several  dig      invocations  to  fetch  a  zone and it will format the output in in a somewhat sensible
       hierarchical style (a tree).

       Information extracted from the DNS relies on being possible to fetch a zone through a zone  transfer.  If
       the  DNS  servers  for  the requested domain do not allow file transfers dns_tree     will not be able to
       obtain information from the zone.

       All data obtain is cached in ~/.DNS_BROWSE with an approximation of the usual DNS caching rules.   Remove
       all files in that directory to prematurely flush the cache.

OPTIONS

       A summary of options is included below.

       -t TYPE   Show  only  records  of TYPE. This argument can be repeated to indicate multiple types. Use the
                 "all" type to print all the known types.

       -m MATCH  Show only records in which the first component matches the PERL regexpt MATCH.

       -h        Show summary of options.

       -v        Enable verbose mode. All DNS requests are printed in the standard error.

       -d        Enable debug output. Presents internal information of the program

       -f        Override warnings (force).
