What Are The Common TCP/IP Application Protocols?
• DHCP Dynamic Host Configuration Protocol (DHCP) allows IP addresses to be allocated to hosts on an as-needed basis. The conventional scheme of allocating a permanent fixed IP address to every host is wasteful of addresses in situations where only a relatively small number of hosts are active at any given time. DHCP lets a host ‘borrow’ an IP address from a pool of IP addresses; when the address is no longer needed it is recycled and made available for use by some other host. DHCP also allows a host to retrieve a variety of configuration information at the same time as it acquires an IP address. DCHP depends on UDP to carry packets between the client and server tasks. DHCP is defined by RFC’s 2131 and 2132. A widely-used implementation of DHCP can be downloaded from
