Sorry for my poor English.
My description was not suitable to explain what I want to do.

For example, nameserver for my domain '' registered
as following.      nameserver =      nameserver =      nameserver =      nameserver =      nameserver =

The data for zone '' is currently managed on, which configured as 'type master' in named.conf.

I want to change the master to ''.
Because I want to manage all hostname and IP address in my domain
including private address via Web(CGI) on ''.

And this '' placed internal LAN, which has private
It can communicate with '' only.

So, it seems '' is just like a master server from
outside of my domain '', this is what I want to realize.

The NS record for the zone '' is described as
        IN      NS
        IN      NS
        IN      NS
        IN      NS
        IN      NS

If I set "notify yes;" in named.conf on '',
'' tries to send NOTIFY message to all of above
Or I set "notify no;", named ignores "also-notify" clauses.

But I want to let '' send NOTIFY message to
'' only, and I want to prevent to send NOTIFY to
other four servers(,,,

Could I tell you what I want to do ?

Sorry, I do so in future including this time.
