14.16.17 DHCP
Dynamic Host Configuration Protocol (DHCP) is a communication protocol that lets network administrators to
manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization’s network.
Using the Internet Protocol, each machine that can connect to the Internet needs 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 at 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 to supervise
and distribute IP addresses from a central point and automatically sends a new IP address when a computer is
plugged into a different place in the network.
To configure DHCP server, move the cursor to dhcp and press enter.
