Hi All,
 
Is it possible for me to add multiple dns64 in options? I want to have different IPv6 prefix for each IPv4 network address.
If not, what are the other possible options?
 
Thanks,
Rock

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?

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

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