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).
