The [[DNS]] is a hierarchical system designed to allow humans to use text strings to access content or services in place of IP addresses on a global information network. Operating systems have been distributed for decades with the listing of default DNS servers to use as the authoritative place to obtain an answer when searching for a [[TLD]]. There are 13 [[Root Server Operator]]s in that file, and they comprise the [[Internet]]'s main DNS root. In addition to the Internet's main DNS root working in agreement with [[ICANN]], several organizations operate Alternative Root Servers (often referred to as "alt roots"). Each alternative root has its own set of root nameservers and its own set of TLDs. | The [[DNS]] is a hierarchical system designed to allow humans to use text strings to access content or services in place of IP addresses on a global information network.
