DHCP (Dynamic Host Configuration Protocol) is a network management protocol which is used to dynamically assign an Internet Protocol (IP) address to any device on a network so they can communicate using IP. DHCP automates and centrally manages these configurations rather than requiring network administrators to manually assign IP addresses to all network devices. It can be implemented on small local networks as well as large enterprise networks.
DHCP will assign new IP addresses in each location when devices are moved from one place to another place, which means network administrators do not need to manually configure each device with a valid IP address or reconfigure the device with a new IP address if it moves to a new location on the network. Versions of DHCP are available for use in Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6).
DHCP configuration of the following network is shown below—-
After assigning the IP address of the default gateway of the Router fa0/0 interface, we will enter the following command to the router CLI—–
Here “cisco” is any name used for the name of the pool.
Then we can see that the host pc automatically pick the IP address from the network.
