Global Traffic Manager (GTM)/DNS monitoring of Wild-IP pool members involves using various health-checking and monitoring techniques to ensure that IPs in a pool are responsive and able to handle traffic effectively. Wild-IP pools refer to IP pools where the exact identity of members may not be pre-defined or fixed, and they can dynamically change.

    Thanks waqas34 for your advice ! Based on my description of our setup, what the method the local DNS uses to monitoring the remote wild-ip pool member ? The member IP is fixed, and tried to use tcpdump to capture the monitoring probe, but nothing was captured, don't know how locl DNS monitor the pool members. Please advise, if you need more info about our setup/config, I can provide, thanks in advance!
