Hi Gaurav,

 

My goal is to mapped IPv6 to a specific IPv4 network that is why I use a mapped 
{ } in options.

 

Regards,

Rock

Why u are using mapped{} options in dns64 conf ???

 

What we are doing is:

 

dns64 2001:db8:5200::/96 {

Clients {

   2001:db8:1000:10::/64;

   2001:db8:20:10::/64;

    …….

   };

};

Hi Phil,

 

Thanks. We have multiple IPv4 networks and we want to have different IPv6 
address network mapping for each IPv4 manily for security reasons.

 

Based from your reply, I can add multiple dns64 in options. Should I configure 
it like this?

 

options {

   directory "/var/cache/bind";
   auth-nxdomain no;
   listen-on-v6 { any; };
   allow-query { any; };
   

dns64 2001:db8:1:ffff::/96 {
    clients { any; }; 
    mapped { 10.10.10.0/24; };

    };

    dns64 2001:db9:1:ffff::/96 {
    clients { any; };
    mapped { 10.10.20.0/24; };

    };

  };

 

Thanks

Yes.

I don't know what the means, but the dns64 option takes a quite comprehensive 
set of ACLs to match client and original packet A address(es) as well as other 
options. Perhaps you should read the ARM?
