It's usually referred to by some pointer to RFC 2317, e.g. "classless
reverse delegation in the style of RFC 2317". I am not aware that
anything snappier than that has become standard. "CNAME hack" is
*very* ambiguous, apart from being unnecessarily pejorative.

There's nothing BIND-specific about it, of course.
