What is DNS and what does it do?
DNS (Domain Name System) resolves a name to an IP address allowing the user to browse to that site into a simpler manner. For example well you know yahoo.com as yahoo.com your computer knows yahoo.com as an IP address (for example 66.159.22.180). In order to make surfing the internet easier and more user friendly DNS associates a name to an IP address. When people say DNS is resolving it means that DNS is “translating” the name typed in into an IP address so that your computer is able to browse to it.
