If you have any suggestions on how this tool might be improved, please email me.

DO Indicates that you want to receive DNSSEC data associated with the query.
AA The responding name server is an authority for the domain name.
QR Indicates that this is a response.
RA Support for recursive queries is available.
AD The response has been authenticated by the server.

MX Lists the mail servers for the hostname.
