  // The registrar notes several more specific domains available in each state,
  // such as state.*.us, dst.*.us, etc., but resolution of these is somewhat
  // haphazard; in some states these domains resolve as addresses, while in others
  // only subdomains are available, or even nothing at all. We include the
  // most common ones where it's clear that different sites are different
  // entities.
