When you log in to a website, you key in the uniform resource locator (URL) into your Web browser and press enter. The URL is a space-holder text for the internet protocol (IP) address you are trying to access. The component for your internet connection is the domain name server (DNS). It changes the text-based URL into the numeric Internet Protocol address of the website you want to access. Open DNS and Google DNS are the most known DNS services available. Both offer dns security and enhanced networking capabilities, but have key variations between them.
