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.
