Do you mean you need a caching only name server?

It is easy.  Here is a step by step guide for configuring a basic caching nameserver (BIND9).

You need to setup views in bind.
Example:
 
view "internal" {
        match-clients { lan_hosts; };		# match hosts in acl "lan_hosts" above
        recursion yes;				# allow recursive queries
        notify no;				# disable AA notifies

        // prime the server with knowledge of the root servers
        zone "." {
                type hint;
                file "db.root";
        };
        // be authoritative for the localhost forward and reverse zones, and for
        // broadcast zones as per RFC 1912
        zone "localhost" {
                type master;
                file "db.local";
        };
        zone "127.in-addr.arpa" {
                type master;
                file "db.127";
        };
        zone "0.in-addr.arpa" {
                type master;
                file "db.0";
        };
        zone "255.in-addr.arpa" {
                type master;
                file "db.255";
        };
        zone "example.com" {
                type master;
                file "internal/example.com.zone";
        };
};

view "external" {

	// "localnets" and "any" are special reserved words
	// "localnets" mean any network address (as opposed to host address) configured
	// on the local network interfaces - "!" means to negate
        match-clients { !localnets; any; };
        recursion no;			# disallow recursive queries
        allow-transfer { dns_slaves; };	# allow "hosts in act "dns_slaves" to transfer zones

        zone "example.com" {
                type master;
                file "external/example.com.zone";
        };
};

Open in new window
