- Even if BIND had negative caching, it wouldn't help much in this case.
- The problem is that there wouldn't be any queries for just "UUCP". Your
- local name server would forward queries for foo.UUCP and bar.UUCP to
- the root servers, which would return a no such domain response. Your
- local server would cache this information for foo.UUCP and bar.UUCP,
- but when it received a query for baz.UUCP, it would still forward it
- to the root servers.
