    Hi Kevin,

     

    This solution creates a listener and forwards to the DNS servers.

     

    My requirement is to resolve the wide-ip in the zone first. If the wide IP doesn't exists, need to forward it to the downstream DNS server. Would this help?

    Greetings, In this situation, BIG-IP DNS checks incoming DNS queries and if the query is for a wide IP, resolves the query. Otherwise, BIG-IP DNS forwards the DNS query to one of the servers in a pool of DNS servers, and that server handles the query.

     

    Give it a try and let us know!
