Thanks for the example.
The IPs in my case cannot be determined in advance. They might be configured
and then changed to any values. I could fall back to create a script to detect
the changes and modify named's config and restart the named service. But that
sounds not so good. I hope named can ignore some specific IP and/or interfaces
while handles the rest.
