Wild Card Listeners ?

Can any one give me an example for the operation of the Wild card Listener ?

I know the definition but I cannot understand it

What is the Role of Bind?"Please don't mention definition only ,I need example"

Why do we use the Wild card Listener in parallel with any other listener ?

How will the F5 GTM REPLY IN THE FOLLOWING CASES:

1-Listener with IP ADDRESS OF THE LDNS IP and the REQUEST IS FOR Wide IP ?

2-Listener with IP ADDRESS OF THE LDNS IP and the REQUEST IS FOR FQDN NOT WideIP ?

3-Listener with IP ADDRESS OF THE LDNS IP and the REQUEST IS FOR FQDN NOT Exist inside the LDNS ?
