#+title: DHCP
|

The Dynamic Host Configuration Protocol (DHCP) is a [[id:c9461f7b-7368-4b88-b90b-2d785fda2159][network]] management [[id:bd5b34ba-aa98-4808-b97b-2376aa7b8866][protocol]] used on Internet Protocol ([[id:f055acfb-05dd-4228-a92a-356240b8c975][IP]]) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a [[id:70899526-8b7d-4976-94fc-cc07c41e550a][client]]–[[id:f2b1d5af-1a7d-47a5-95c8-4a85d558419e][server]] architecture.

|

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. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP.

DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many [[id:d2ff2e45-e1de-4cca-9b59-dfc3ee6afa6f][router]] and residential [[id:d1d940e1-2ddb-405a-8876-2480bdcab749][gateway]]s have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device if the [[id:5fada795-19a3-4ba6-97c0-0b70bd728a2f][operating system]] allows it.

DHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 (IPv6). The IPv6 version of the DHCP protocol is commonly called DHCPv6.
