Dns_tree command-line frontend to dig
dns_tree [-f] [-v] [-d] [-t TYPE] [-m MATCH] DNS_domain
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.
A summary of options is included below.
