Can the GTM be configured to handle an IP for the Wide-IP, vice a hostname request. For example, I hit the listener on 10.1.1.1 and configure the Wide-IP with the same ip 10.1.1.1, then globally balance that IP to send traffic to the available Virtual Server. Thanks, -JAK
You can't use DNS to resolve an IP address to another IP address, which appears to be your goal. It won't work, because the client will never make a DNS request to resolve an IP address, as it is already resolved.
What you need to do is set up your network routing to anycast that address into your network - this is how google's 184.108.40.206 works for example. If you advertise 10.1.1.1 into your network in multiple places, and one falls off, then the network will route it to the other more remote one.
