does authority named require the external name servers?

Hi Chris,

That's what the real question I want to know.
For example, my DNS Servers have lots of domains hosting, all the
zones have the same NS RRs:
ns1.dnsbed.com
ns2.dnsbed.com

But dnsbed.com is not authority resolved by my own nameservers.
So, I was asking when there is not correct entries in /etc/resolv.conf
if named will find the ns1 and ns2.dnsbed.com correctly from the root
hint.

Now I got it, thank you.
