And in the process break local iterative servers as they
don't look at "rd" as a pass through indicator and return
non-authorative answers from the cache which then get
rejected. Hotels are notorious for this misbehaviour.
Presumably they are trying to get you to their sign up
page but intercepting http would be just as effective.
DNS is not such a bandwidth hog as to be worth the effort.
