DHCP or a Dynamic Host Configuration Protocol is a protocol of communication that assigns IP-adresses automatically to all the devices on the web. As soon as the network device joins or leaves the network that is based on the IP principle, DHCP renews the IP-address base automatically. DHCP works in the client-server regime. In such regime server gets the pool of available IP-adresses on the network. DHCP server also provides the network gateway, subnet masks, NS-adresses and sets up the amout of time during which the IP-adress will remain valid. DCHP client gets this parameters and uses them to connect to the existing network.
DHCP allows system administrators to manage the network much easier, without any fears that some address may duplicate. Such option makes network administration more simple and plain and allows to concentrate on other tasks.
