I've seen a US based ISP do its internal management network reverse DNS using '.us' as a suffix, where the hierarchy is like POP name, then city/airport code, then state (eg: CA, NJ, FL), then .us for geographical location of equipment in USA.
The .us domain in question was owned by the same organization but with only a stub zone file published on public facing authoritatiev NS, with the internal zonefile not available to the public.
