DNS Explained

DNS

An internet service that translates domain names into IP addresses. This is the core reason that you can refer to a website by its domain name and not have to remember its IP address.

Your DNS can be managed in a number of different ways.  One common method is through your domain name service (not to be confused with domain name server).
