DHCP – Dynamic Host Configuration Protocol

(DHCP) Dynamic Host Configuration Protocol- is a communications protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses, subnet masks, default gateway, and other IP parameters as nodes come online, as opposed to manually configuring static IP addresses for each device. Servers or routers can act as DHCP servers, but typically only one such device should actively be used at any given time to assign IP addresses on a LAN. This method for dynamically managing and automating the assignment of IP addresses lets a network administrator supervise and distribute IP addresses from a central point and automatically send a new IP address. DHCP uses the concept of a lease or amount of time that a given IP address will be valid for a node.
