4.5 DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa, for example, the IP address of www.zyxel.com is 204.217.0.2. The DNS server
is extremely important because without it, you must know the IP address of a machine before
you can access it. The DNS server addresses that you enter in the DHCP setup are passed to
the client machines along with the assigned IP address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP
to tell a customer the DNS server addresses, usually in the form of an information sheet, when
s/he signs up. The second is to obtain the DNS server information automatically when a
computer is set as a DHCP client.
