It's the nature of OpenDNS that if you send a query to it for *any* hostname
that doesn't resolve, instead of (properly) giving a "no such host" message,
it instead responds with an IP address pointing to one of its own
webservers.

So any failure to resolve a name via WINS will result in it being resolved
to OpenDNS instead, in this situation.
