14.5.1 Introduction to a Network connection
DHCP
Dynamic host con fi guration protocol. DHCP is a communications protocol that lets network administrators manage
centrally and automate the assignment of 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 and, 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 sends a new IP address when a computer is plugged into a different place in the
network.
