DHCP means Dynamic Host Configuration Protocol
DHCP is a protocol that issues IP addresses, it is designed by the Internet Engineering Task Force (IETF). The goal was to provide a robust (dynamic) IP address assignment. DHCP provides automatic configuration of an IP address and often also provides DNS Sereradressen. The DHCP server ensures that no duplicate IP addresses are used within the network. An important goal of DHCP is to reduce the management work in an IP network (for example, an ADSL network).
