Characteristics of Bootp and DCHP. The Bootp protocol is designed for
a network in which each host has a permanent network connection. 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.
