#!/usr/bin/env python3

# Usage: reverse.py <zone_filename>...
#
# This demo script will load in all of the zones specified by the
# filenames on the command line, find all the A RRs in them, and
# construct a reverse mapping table that maps each IP address used to
# the list of names mapping to that address.  The table is then sorted
# nicely and printed.
#
# Note!  The zone name is taken from the basename of the filename, so
# you must use filenames like "/wherever/you/like/dnspython.org" and
# not something like "/wherever/you/like/foo.db" (unless you're
# working with the ".db" GTLD, of course :)).
#
# If this weren't a demo script, there'd be a way of specifying the
# origin for each zone instead of constructing it from the filename.
