DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other network configuration parameters to devices on a network. It allows devices to join a network and obtain necessary network settings without manual configuration.
When a device connects to a network, it sends a DHCP request to a DHCP server. The DHCP server then responds with an available IP address and other configuration information such as subnet mask, default gateway, and DNS server addresses. This process is known as DHCP lease negotiation.
DHCP simplifies network administration by centrally managing and distributing IP addresses, reducing the need for manual configuration. It also supports dynamic IP address allocation, where IP addresses are assigned for a limited period and can be reused when not in use, optimizing address utilization.
In addition to IP address assignment, DHCP can also provide other network parameters like domain name, time server, and network boot server addresses. It ensures that devices on a network have the necessary network settings to communicate effectively and efficiently.
