![]() ![]() It can also be used to deliver a wide range of extra configuration parameters to IP clients, including platform-specific parameters. ĭHCP is based on BOOTP, but can dynamically allocate IP addresses from a pool and reclaim them when they are no longer in use. This introduced the concept of a relay agent, which allowed the forwarding of BOOTP packets across networks, allowing one central BOOTP server to serve hosts on many IP subnets. ![]() RARP was superseded by the Bootstrap Protocol ( BOOTP) defined in RFC 951 in September 1985. It required that a server be present on each individual network link. Acting in the data link layer it made implementation difficult in many server platforms. The Reverse Address Resolution Protocol (RARP) was defined in RFC 903 in 1984 for the configuration of simple devices, such as diskless workstations, with a suitable IP address. ![]() The IPv6 version of the DHCP protocol is commonly called DHCPv6. Within a local network, a DHCP server assigns a local IP address to each device.ĭHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 ( IPv6). Most residential network routers receive a unique IP address within the ISP network. Many routers and residential gateways have DHCP server capability. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP.ĭHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. The technology eliminates the need for individually configuring network devices manually, and consists of two network components, a centrally installed network DHCP server and client instances of the protocol stack on each computer or device. ![]() I'm using isc-dhcp-server version 4.3 (isc-dhcpd-4.3.The Dynamic Host Configuration Protocol ( DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture. ![]()
