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.
The gateway address can be automatically determined using Dynamic Host Configuration Protocol (DHCP). DHCP allows a host to obtain network information from a server. The host contacts the server to obtain an IP address and Default Gateway address. DHCP Servers are normally provided by Internet Service Providers (ISPs).
A network administrator may configure DHCP by allocating specific IP addresses based on MAC address. DHCP is not the only technology used to assign IP addresses dynamically. Bootstrap Protocol is a similar protocol and predecessor to DHCP. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol.
It does not typically provide Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services, but manages information for these components. [1] Additional functionality, such as controlling reservations in DHCP and other data aggregation and reporting capabilities, is also common.
More commonly addresses are assigned by a DHCP server, often built into common networking hardware like computer hosts or routers. Most IPv4 hosts use link-local addressing only as a last resort when a DHCP server is unavailable. An IPv4 host otherwise uses its DHCP-assigned address for all communications, global or link-local.
It is effectivelys a client of the external DHCP servers owned by the ISP. Controllers for home automation or smart home hubs act as a gateway and router for low-power wireless networks of simple, non-data-intensive devices such as light bulbs and locks. [citation needed]
dhcpd (an abbreviation for "DHCP daemon") was a DHCP server program that operates as a daemon on a server to provide Dynamic Host Configuration Protocol (DHCP) service to a network. [3] This implementation, also known as ISC DHCP, is one of the first and best known, but there are now a number of other DHCP server software implementations available.
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
