Adding a DNS server
I'm sure most of you are familiar with the purpose of a 
Domain Name System
 
(
DNS
) server. Its simplest definition is that it's
 a service that's responsible for 
matching an IP address to a domain or hostname. When you connect to the internet, 
name-to-IP matching happens constantly as you browse. After all, it's much easier to 
connect to 
https://www.google.com/
 using its domain name than it is to remember 
its IP address. When you connect to the internet, your workstation or server will 
connect to an external DNS server in order to figure out the IP addresses for the 
websites you attempt to visit.
