What kind of DNS server should I make?

Hello All,

I have created a virtual lab environment to practice Linux. This includes

1. Local LAN (192.168.1.0/24, Zone: cntnix.lan)
2. KVM LAN (192.168.122.0/24, Zone: kvmlab.lan)

I have also setup an Authoritative Bind DNS server in cntnix.lan zone with IP address 192.168.1.7, which resolves both cntnix.lan and kvmlab.lan zones. No problem here.

But the problem is, according to this site, and others are that they mention the authoritative server should not be recursive.

If I set 'recursion no;' in named.conf, I cant resolve the outside world.

Code:$ dig google.com

forwarders { 8.8.4.4; 8.8.8.8; };

zone "cntnix.lan." IN {
type master;
file "cntnix.lan.fwd";
allow-update { none; };
};

zone "1.168.192.in-addr.arpa." IN {
type master;
file "cntnix.lan.rev";
allow-update { none; };
};

zone "kvmlab.lan." IN {
type master;
file "kvmlab.lan.fwd";
allow-update { none; };
};

zone "122.168.192.in-addr.arpa." IN {
type master;
file "kvmlab.lan.rev";
allow-update { none; };
};...which is working fine, but it also makes a caching server, forward only server and authoritative server - A cocktail server. How do I deal with this problem.

All I want is
"An authoritative server which resolves local zones, but also resolves outside world"

Thanks
