It makes it more convenient to refer to a machine by name than by its IP address. Network naming can be hierarchical in nature, such as the Internet's Domain Name System. Indeed, the Internet employs several universally applicable naming methods: uniform resource name (URN), uniform resource locator (URL), and uniform resource identifier (URI).
