DNS Resolution with the RESOLVER::name_lookup Command
When 15.1 released, we deprecated the RESOLV::lookup command. It still works, but there is no commitment that it will continue to work, so now is a good time to begin migrating your code away from it...
I meant even if RESOLV::lookup should be still supported with 15.x and 16.x. I opened an F5 case but they still haven't reply. I hope you are able to help me. Thanks
