Dynamic Host Configuration Protocol (DHCP) is a method of assigning IP addresses dynamically. Many routers contain the option for a DHCP server. DHCP allows client computers to be configured automatically; when a computer is switched on, it searches for a DHCP server and obtains TCP/IP setup information. Network configuration changes are done centrally at the server. The administrator does not need to apply the change to every computer in the network. The clients will be updated when the request information from the DHCP server during their boot-up cycle. For example, if it is necessary to reconfigure a private addressing scheme in order to merge the network with the network in another store, all clients will automatically start using the new addresses the next time they boot-up. Some ISPs will require the use of DHCP as a prerequisite for using their network.
