In large, well organized, academic or ISP (Internet Service Provider) networks you will sometimes find that the network people have set up a forwarder hierarchy of DNS servers which helps lighten the internal network load and the load on the outside servers as well. It's not easy to know if you're inside such a network or not. It is however not important and by using the DNS server of your network provider as a ``forwarder'' you can make the responses to queries faster and less of a load on your network. If you use a modem this can be quite a win. For the sake of this example we assume that your network provider has two name servers they want you to use, with IP numbers 10.0.0.1 and 10.1.0.1. Then, in your named.conf file, inside the opening section called ``options'', insert these lines:
forward first;
forwarders {
10.0.0.1;
10.1.0.1;
};
There is also a nice trick for dialup machines using forwarders, it is described in the qanda section.
Restart your nameserver and test it with dig. Should work fine.
