DHCP stands for Dynamic Host Configuration Protocol. It's a network protocol that allows network equipment to auto assign IP addresses to various devices within a given network. In other words, enabling DHCP on your router will make it easy to provide and distribute IP addresses across your network without the hassle of manual configuration. This is ideal for a couple of reasons. First, it saves time. Second, it ensures that no two devices are assigned the same IP address. Overall, DHCP makes the network easier to manage.
