What is a DNS and why do I need it?

DNS, or Domain Name System, is the translation of a website or email’s human-friendly location name into a computer-friendly location name, or the website’s URL into an IP Address. Computers read locations by IP addresses. An example of an IP Address would be 74.208.168.187 for the website you are currently on. These addresses are always in the same numerical format and can be used to direct your internet browser to the files required to view a website. As the exclusive use of IP Addresses to access websites would be difficult, instead of typing in the IP Address, the DNS allowed you to enter in www.OptimumSystemsOnline.com which was then translated into the IP Address location.
