phony TLD

[Christine Tran]

I didn't do this, but someone did, and it's causing trouble:

zone "nutcase.biz" in {
	type forward;
	forwarders {x.y.z.z;};
};

Clearly .biz is not a recognized TLD, I don't even know how they did it, using
Win2K.  Result is named tries to go to root servers.  Questions:

1) Is the legit TLD (.com, .org, etc.) hardcoded into BIND?
2) If no, why doesn't the above work?  named is explicitly told to go to
   x.y.z.z for *.nutcase.biz.
3) Why is named going to root servers?  If legit TLD is hardcoded, named
   should come back with "no server for .biz domain" and end there, instead
   of going to root servers for referals?

named's behavior is inconsistent with both case of hard-coded, and not-hard-coded.
What is it doing?  Running BIND 8.2.2p5.
