The Basics of Networking | Network Protocols | DHCP

The Simple Definition Dynamic Host Configuration Protocol (DHCP) is a network protocol used to automatically assign IP addresses to devices on a network. DHCP is used to simplify the management of IP addresses and reduce the likelihood of IP address conflicts. When a device, such as a computer or a smartphone, connects to a network, it sends out a broadcast message requesting an IP address. A DHCP server, which is typically located on a router or a dedicated server, receives the request and assigns an available IP address to the device. The DHCP server also assigns other network configuration information, such as the subnet mask, default gateway, and DNS server IP addresses.
