	While this is indeed true, there's a whole lot more to this
than meets the eye. Once one gets a primary and a secondard name
server running the rules change a bit. At this point one can
easily create a network of name servers and thus lighten the load on
the primary and secondary name servers and Bind provides the
functionality to do just this. All one has to do is, after making
arrangements for additional name servers, add the following to their
name servers named.conf file:

	forward first;
	forwarders {
		xxx.xxx.xxx.xxx
		xxx.xxx.xxx.xxx
		etc...
	}

	Using forwarders lightens the load on the primary name
servers and increases response times by spreading the traffic over a
hierarchy  - a network - of name servers. For more information check
