Bind vs GTM DNS

Here is a short answer on the resolution process on GTM.

 

 

All DNS requests will come into the GTM device on port 53. There is a object created on the GTM called a "Listener" that is a self-ip address that will process DNS requests. When the DNS request comes into the Listener, GTMD first tries to match it against a Wide-IP first, if there is not a Wide-IP that matches the FQDN, then the DNS request will get dropped to BIND. If there is no match on a zone file, then no resolution will occur.

 

 

ZoneRunner is used to manage the zone files, and the daemon for that is zrd.

 

 

Hope this helps.
