Might want to handle reverse DNS lookups.

Might want to print the DNS server being used too.

This person is using dict to dump the records: http://stackoverflow.com/questions/5903097/python-dns-resolver-get-dns-record-type

Looks like other exceptions may be raised:

@raises Timeout: no answers could be found in the specified lifetime
        @raises NXDOMAIN: the query name does not exist
        @raises YXDOMAIN: the query name is too long after DNAME substitution
        @raises NoAnswer: the response did not contain an answer and
        raise_on_no_answer is True.
        @raises NoNameservers: no non-broken nameservers are available to
        answer the question."""

Also, custom DNS server is not yet supported.
