@ehsandeep, I forgot to update the client tests as well. Those have now been added.

One possible limitation to my implementation is that this will result in duplicate entries in the output.

For instance, example.com resolves to three IPs, but we prefer domain in the output, which would display example.com three times instead of each IP. The ASN and IP ranges would still reflect the difference, though, so this might be acceptable.
