What is the primary function of a DHCP server in a network?

The primary function of a DHCP server in a network is to assign IP addresses to devices on the network. DHCP, or Dynamic Host Configuration Protocol, automates the process of IP address allocation, reducing the administrative burden of manually assigning static IP addresses to each connected device. When a device connects to the network, it sends a request to the DHCP server, which then provides an available IP address from its pool of addresses. This not only facilitates easier management of IP addresses but also helps to avoid conflicts that can arise if multiple devices are assigned the same address.

In addition to assigning IP addresses, DHCP can deliver other essential configuration information such as the subnet mask, default gateway, and DNS server information, further streamlining network setup for clients. This functionality is crucial in both small and large networks, ensuring that devices can effectively communicate within the network and have access to necessary services.
