Ip Configuration By Dhcp - NETGEAR DG814 DSL Reference Manual

Reference Manual for the Model DG814 DSL Modem Internet Gateway

IP Configuration by DHCP

When an IP-based local area network is installed, each PC must be configured with an IP address.
If the PCs need to access the Internet, they should also be configured with a gateway address and
one or more DNS server addresses. As an alternative to manual configuration, there is a method by
which each PC on the network can automatically obtain this configuration information. A device
on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP
server stores a list or pool of IP addresses, along with other information (such as gateway and DNS
addresses) that it may assign to the other devices on the network. The Model DG814 gateway has
the capacity to act as a DHCP server.
The Model DG814 gateway also functions as a DHCP client when connecting to the ISP. The
router can automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway
address if the ISP provides this information by DHCP.
