Do I need DHCP?

You are likely to be already using DHCP protocols as a component of your home or business network as it releases you from having to assign fixed IP addresses to every new device which joins the network yourself.

 

Although much easier in smaller contexts, this task would be especially hard for any larger organisations that should expect hundreds of devices to be connected to a network. Each and every one of these devices would require a distinct IP address - a daunting task made even tougher with organisations without local IT teams.

 

DHCP automates the process through a dynamic IP assignment - granting new IP addresses as devices join the network and, crucially, delisting them automatically once a device disconnects.

Realistically, there are very few reasons why you shouldn't be using DHCP, yet, in some cases, it could be useful to assign manual addresses. Some devices benefit from having static IP addresses, such as scanners, printers, file transfer servers, and many other devices that should always have a constant connection with a network. In such instances, a dynamic IP address, using DHCP, would require a device to update its connection settings every time it tried to communicate with the printer.
