[SOLVED] drill as nslookup replacement

I'm stuck with a script, where I have to check if a domain/subdomain exists.

nslookup  $domain >/dev/null 2>/dev/null; echo $?
drill $domain >/dev/null 2>/dev/null; echo $?

The old way with nslookup works fine, exit code is non-zero for invalid/non-existing domains.
The new way with drill always gives me status 0 :-(

Any ideas ?
Is there a better solution ?

Thanks very much.
