BIND NXDOMAIN

Hi,

 

We are investigating the features of NXDOMAIN redirect as explained in

https://kb.isc.org/article/AA-00376/0/BIND-9.9-redirect-zones-for-NXDOMAIN-r
edirection.html

 

We are running BIND 9.9 stream.

 

My question is, Is it possible to "whitelist" particular domains?, The ARM
does

Not refer to any form of whitelisting

 

 

zone "." {
        type redirect;
        file "db.redirect" ;
};

 

So if my db.redirect has the below for Status=NXDOMAIN to return the below
RR A

 

*. IN A 10.100.100.4

 

 

But I want to return status:NXDOMAIN for only the below domains

 

*.nooverride.com.au

*.nxreturn.com.au

 

Is this possible? If not a modification to query.c is the only option.

Has anyone got a src patch for this feature?

 

Thanks

Neil
