What is a DNS?
DNS stands for "Domain Name Server". It translates domain names into IP addresses that computers understand. For example, if someone wants to access our website (www.hostreview.com), the DNS will translate the domain into the IP address 66.175.1.6 , which will allow the computer to locate our web server. Domain Name Service (DNS) is the system by which hosts on the Internet have both domain name addresses (such as blueleaf.prairienet.com) and IP addresses (such as 66.175.1.6). DNS is the means by which you are able to type in an easily remembered name in order to go to a URL, instead of using an IP address. The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address - just like a telephone number - which is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol"). IP Addresses are hard to remember. The DNS makes using the Internet easier by allowing a familiar string of letters (the "domain name") to be used instead of the arcane IP address. So instead of typing 66.175.1.6, you can type www.hostreview.com. It is a "mnemonic" device that makes addresses easier to remember.
