DHCP Server
10.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. You can
configure the NBG4115’s LAN as a DHCP server or disable it. When configured as a
server, the NBG4115 provides the TCP/IP configuration for the clients. If DHCP
service is disabled, you must have another DHCP server on your LAN, or else the
computer must be manually configured.

10.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:A0:C5:00:00:02. Find out the MAC addresses of your
network devices if you intend to add them to the DHCP Client List screen.
