What is the function of DHCP in networking?

The function of DHCP, which stands for Dynamic Host Configuration Protocol, is to dynamically allocate IP addresses to devices on a network. When a device connects to the network, DHCP automatically assigns it an IP address from a predefined range, known as a DHCP scope. This eliminates the need for manual IP address configuration, reducing errors and improving network management efficiency.

Dynamic IP address allocation allows devices to join and leave networks seamlessly without requiring a network administrator's intervention for each device. This is particularly beneficial in environments with many devices that frequently connect and disconnect, such as in offices, schools, and public spaces.

Static IP address allocation does not align with DHCP's purpose, as static allocation involves manually assigning fixed IP addresses for devices, which is typically used for devices that require constant IP addressing, like servers or printers. Routing of network traffic is a separate function that involves directing data packets between devices and networks, but it is not the role of DHCP. Wireless signal enhancement refers to improving the quality and range of wireless signals, which is unrelated to IP address allocation.
