DHCP (Dynamic Host Configuration Protocol)?

The Dynamic Host Configuration Protocol (DHCP) is utilized on Internet Protocol (IP) networks for allotting IP addresses and other communication parameters to devices associated with the network utilizing a client–server design. DHCP can be carried out on networks ranging in size from residential networks to large campus networks and regional ISP networks. DHCP depends on a user-server model and is dependent on discovery, request, and ACK.
