Setting up a DHCP server for serving 
IP addresses
Most network appliances you purchase nowadays often come with their own DHCP 
server, and allow you to configure it via a web console. Often, this is totally fine and 
meets your needs. In my experience though, network appliances you purchase can 
be very hit or miss. Some of them are great, while others are not so impressive. One 
of the main problems is that manufacturers will often stop supporting the hardware 
prematurely, exposing your network to unpatched vulnerabilities. It's important 
to always purchase network hardware that's future-proof. Or, you can set up your 
own router with the features that you need. Although the burden of management is 
placed on you, this gives you ultimate flexibility. Ubuntu servers make great DHCP 
servers, and rolling your own server is actually easier than it sounds. And that's 
exactly what we're going to work through in this section.
