Answer DNS query

Hello guys,   I am trying to make an iRule where when I receive any FQDN in the listener on GTM, it responds with just one IP address. Can anyone give me a tip how to do it? I am trying to use DNS...

This can be solved without an iRule. Do you always want to respond with just that address (i.e., 1.1.1.1 in your example)? If so, use the GTM Pool LB method "Fallback IP", and set it to 1.1.1.1.
