DHCP Overview	Dynamic Host Configuration Protocol (DHCP) is designed to provide a
	centralized approach to configuring IP addresses and parameters.
	When a workstation is configured for automatic assignment of IP
	addresses, it broadcasts a request out on the LAN. The DHCP Server
	responds with:
	■ An IP address for the workstation.
	■	The domain name.

■ The IP addresses of the default router, two DNS Servers, and two WINS Servers.

The assignment of an IP address to the workstation is for a specified period of time, referred to as the lease period. Before the lease is set to expire, the workstation will send a request to the server to extend the lease period. The server maintains a list of assigned IP addresses and the duration period of leases. When a lease expires, the corresponding IP address can be reassigned to another workstation.
