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.
IP address. An Internet Protocol address ( IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1] [2] IP addresses serve two main functions: network interface identification, and location addressing .
Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers. 7. Application layer. 6. Presentation layer. 5. Session layer. 4. Transport layer.
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.
Link-local address. 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 ...
Every network host is a node, but not every network node is a host. Network infrastructure hardware, such as modems, Ethernet hubs, and network switches are not directly or actively participating in application-level functions, and do not necessarily have a network address, and are not considered to be network hosts.

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.
