Configuration

Characteristics of Bootp and DHCP. The Bootp protocol is designed for a network in which each host has a permanent network location. It is not adaptable to a mobile computing environment.

The Dynamic Host Configuration Protocol (DHCP) manages the allocation of TCP/IP configuration information by automatically assigning IP addresses.When a device connects to the network, it requests an address from the DHCP server. In dynamic mode, the address is used by the device for a specified period of time. The time period depends on the situation; one device may only need the address for an hour, while another device may use the same address for several days. DHCP is more suitable in environments where the number of IP addresses needed exceeds the number available. It also allows a device to obtain its configuration information, such as the IP Address and Subnet Mask, in one message, reducing the demand on the network.

A static IP address is a unique address that is assigned to one client only.

Static addresses are used for an extended time period.
