Performs a domain lookup using the edns-client-subnet option that adds
support for adding subnet information to the query describing where the
query is originating. The script uses this option to supply a number of
geographically distributed locations in an attempt to enumerate as many
different address records as possible. The script also supports requests using
a given subnet.
