we will see how to configure a DHCP Server with Packet Tracer Router.A DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks. DHCP is an enhancement of an older protocol called BOOTP.DHCP is an important part of the DDI solution (DNS-DHCP-IPAM).The DHCP service brings three key values: 1) Operation tasks are reduced: the network administrator no longer needs to manually configure each client before it can use the network 2) The IP addressing plan is optimized: addresses no longer being used are freed up and made available to new clients connecting 3) User mobility is easily managed: the administrator doesn’t need to manually reconfigure a client when its network access point changes.
