7.2.2 DHCP Server

Dynamic Host Configuration Protocol (DHCP) is a communication protocol that allows network administrators to centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization’s network. Internet Protocol requires that each machine that can connect to the Internet has a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each

machine.

Without DHCP, the IP address must be entered manually for each computer. If computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically send a new IP address when a computer

is plugged into a different place in the network. If the DHCP server is enabled, you have to setup the following parameters for processing DHCP requests from clients.

The embedded DHCP server assigns network configuration information for up to 253 users accessing the Internet at the same time.

IP type:

Fixed

IP Address:

192.168.1.1

Subnet Mask:

255.255.255.0

Host Name:

SOHO

 

Some ISPs require the host name as identification. Check

 

with your ISP to see if your Internet service has been

 

configured with a host name. In most cases, this field can be

 

ignored.
