1. Frontends to DNS search. This package provides two programs to make user lookups on DNS servers: dns_tree and dns_browse. dns_tree is a command-line-based front-end to dig. It replaces the several dig invocations necessary to fetch a zone, and it formats the output in a somewhat sensible hierarchical style (a tree). dns_browse is a GUI front-end to dns_tree. It allows point-and-click DNS browsing and makes it easy to expand/compress hierarchies in one or more DNS zones. From Debian 3.0r0 APT
