Module 3: Domain Name System (DNS)


The domain name system (DNS) tells your domain name what hosting account to connect to.  An example of a DNS would be ns1webhostingforstudents.net and ns2webhostingforstudents.net.

When you get a hosting account it will tell you the DNS for the server.  Then you would add these DNS settings to your domain name with your domain name registrar.
