Configure sub-domain delegation

[Mad_1]

I would like to configure a sub-domain delegation in my primary DNS server (running on HP-UX 11.0). I know it can be done by adding NS records in the 'db' files. However, the 'db' files are translated from the host file /etc/hosts each time when DNS record updated, and those NS records were gone.

How can I configure the delegation in /etc/hosts or in named.conf or any other way I can do?

Thanks.

DNS is not updated by entries in /etc/hosts, unless you build your "db" files using hosts_to_named (see man pages).

What version of BIND are you running?

The BIND version is 8.1.2. I have mentioned that those 'db' files are translated from /etc/hosts (i.e. hosts_to_named).

Other than direct add entries to 'db' files, is there any way to configure the delegation.

e.g. named.conf

Is there anyone has experience in configuring sub-domain delegration?

Thanks
