This includes subnet mask information, default gateway IP addresses and domain name system ( DNS) addresses.ĭHCP is a client-server protocol in which servers manage a pool of unique IP addresses, as well as information about client configuration parameters, and assign addresses out of those address pools. How DHCP worksĭHCP runs at the application layer of the Transmission Control Protocol/IP ( TCP/IP) stack to dynamically assign IP addresses to DHCP clients and to allocate TCP/IP configuration information to DHCP clients. While the adoption rate of IPv6 was slow, by July 2019, more than 29% of Google users were making inquiries using IPv6. IPv6 became an industry standard in 2017 - nearly 20 years after its specifications were first published. Versions of DHCP are available for use in IP version 4 ( IPv4) and IP version 6 ( IPv6). DHCP can be implemented on small local networks, as well as large enterprise networks.ĭHCP will assign new IP addresses in each location when devices are moved from place to place, which means network administrators do not have to manually configure each device with a valid IP address or reconfigure the device with a new IP address if it moves to a new location on the network. DHCP automates and centrally manages these configurations rather than requiring network administrators to manually assign IP addresses to all network devices. Gillis, Technical Writer and EditorĭHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an Internet Protocol ( IP) address to any device, or node, on a network so they can communicate using IP.
