This is perfectly fine on the SAME machine as the one where the cache
DNS runs -- you may also just use the IP address (of that same machine.)

I take it you are running this on a Workstation (non-Server) and so cannot
just run the Microsoft DNS server.

10%? -- unless you are a spammer with very dirty mailing lists (lots of
invalid
domains) then this is totally unacceptable and indicates you should just
avoid the ISP DNS completely.

If you use an internal DNS (for AD etc.) then you should configure your
internal clients to use STRICTLY that internal DNS and let it worry about
external resolution. ( I am assuming that is not your case however.)
