It just means some nimrod was too lazy to create a separate 137.216.61.in-addr.arpa zone in their
nameserver. They're just throwing everything into in-addr.arpa and claiming authority for that whole
namespace. Fortunately, you're running a version of BIND that doesn't get confused by such idiocy.

That isn't a lot to go on. Could you be more specific about what problems you're having? You've checked
your nameserver logs, right?
