DNS is short for Domain Name System. It essentially is a system that takes domain names and associates them with the IP address where they are hosted. This makes it a lot easier to find websites on the internet, for example, without DNS if you wanted to read the information on a website you would have to remember its IP address of perhaps twelve digits, and type that into your internet browser. DNS eliminates that hassle, and you only have to remember the domain name of the website that you would like to visit. Remembering something like PingPipe.com is certainly easier than remembering a 12 digit number. In a lot of ways DNS is like the phone book of the internet as it translates numbers to names. It is better than the phone book in several ways, though, perhaps the best example is that when a change is made to a website's DNS, that information is usually updated in the records of every internet provider in the world in less than 72 hours. (this is called DNS propagation, bythe way). You use the DNS information of your ISP or domain name registrar, or create your own DNS Name Servers on your dedicated server or Virtual Private Server (VPS) using your own domain name for the NS1 and NS2. If you are using a control panel like Cpanel it is really easy to setup, the PingPipe Internet support team is always available to answer any questions or provide any needed assistance.
