Understanding DHCP

On any computer network, there are many end devices, network intermediary devices, and even servers. Each device requires an IP address to exchange messages and share resources with each other. A network administrator usually assigns static IP addresses to devices that provide a service or resource to the network – devices such as switches, routers, firewalls, and servers. When a device is assigned a static IP address, it allows network administrators to remotely access and manage the device, as the address will never change.

Since a network is mostly made up of a computer and other end devices that often change physical locations, it's not wise to always assign static IP addresses to such devices. When a device with a static IP address is moved to another location, whether physical or logical, the IP scheme at the new location may not be the same as the IP configurations on the device itself. Therefore, the network administrator will be required to...
