Wide-IP is actually a listener object. As soon as you create a new wide-ip, GTM automatically creates its A record to the matching zone using bind. You can view the a zone's SOA, NS and A records using zonerunner tab. Zonerunner is nothing but a GUI to manage bind engine.

 

On your DNS (LDNS), you either setup a delegation towards GTM or create forwarding pointing to GTM, depending on the flavor of your setup.
