Establishing an internal root server

[Steve Hammill]

Thanks to everyone who helped me get my DNS server working last
weekend.  Now I'm hoping to get it totally right.

We do not have an Internet connection.  Can I establish our primary as a
pseudo-root by giving the A server in db.cache my DNS address and
deleting the rest?

Or is there a "proper" way to do it.  I couldn't find it in DNS/Bind,
but I might not have been using the correct terminology.

Again TIA,
Steve
