GTM Listener IP - Best Practice

I believe the answer is already in what you typed... e.g.

"A listener object that is not defined as a self IP address cannot direct name resolution requests to BIND"

If you don't require that (and I usually make sure that requests not serviced by GTM are dropped myself), then you have no issues AFAIK.

Possibly it's listed as not best practice because if GTM can't resolve it, you won't get any answer, and whoever wrote it wanted to make sure at least SOMETHING was given back (e.g. for addresses that ARE NOT serviced by GTM - i.e. not WideIP's).

However for most of the installs I've done, that was the DESIRED effect anyway... Because I don't like running GTM's inline with normal DNS services - i.e. I like my GTM's to be serving ONLY WideIP's.
