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 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. It is not just the IPv6 equivalent of the Dynamic Host Configuration ...
DHCP snooping. In computer networking, DHCP snooping is a series of techniques applied to improve the security of a DHCP infrastructure. [1] DHCP servers allocate IP addresses to clients on a LAN. DHCP snooping can be configured on LAN switches to exclude rogue DHCP servers and remove malicious or malformed DHCP traffic.
In computer networking, a link-local address is a network address that is valid only for communications on a local link, i.e. within a subnetwork that a host is connected to. Link-local addresses are most often unicast network addresses assigned automatically through a process known as stateless address autoconfiguration ( SLAAC) or link-local ...
Dynamic IP addresses are assigned by network using Dynamic Host Configuration Protocol (DHCP). DHCP is the most frequently used technology for assigning addresses. It avoids the administrative burden of assigning specific static addresses to each device on a network.
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.
For example, unless an address is preconfigured by an administrator, when an IP host is booted or connected to a network it needs to determine its IP address. Protocols for such reverse correlations include Dynamic Host Configuration Protocol (DHCP), Bootstrap Protocol (BOOTP) and, infrequently, reverse ARP. See also. History of the Internet
A DHCP server typically runs on the router with end devices as its clients. The router itself is a client of the external DHCP servers owned by the internet service provider . All DHCP clients request configuration settings using the DHCP protocol in order to acquire their IP address , a default route and one or more DNS server addresses.
