Does bind9 support adding acl and view through commands, not by updating config file?

do you mean, the same domains with different content, depending on clients'
IPs? That's common multiple-view setup
(nothing special or intelligent).

Why? Do you have that many clients constantly with changing IPs?

Maybe they could use local DNS server talking to your DNS server using TSIG,
and instead of IPs you'd define TSIG keys.

>So i want to know whether have commands or API to add acl and view like the command "rndc addacl" or "rndc addview"?

I'm afraid for now there's no  way to make this via rndc.
You'll have to generate named config per-client.

I don't understand how/why it should affect other zones.
