When you say "legitimate corporate dns servers", do you mean that they're
part of your corporation (i.e. in a different department)? If so, they're
probably just trying to optimize inter-department lookups.
If they're in some other company, it could be a misconfiguration of some
kind. You could try writing them to perform a sanity check.
