What is URL? Every server on the internet has an IP number, a unique number consisting of four parts separated by dots. The IP number is the server’s address . .
At times the number keeps changing hence it is harder for people to remember number than to remember word combinations. So, addresses are given “word-based” addresses called URL. The URL and the IP number are one and the same. A URL is an address that shows where a particular page can be found on the World Wide Web.
URL is an abbreviation for 'Uniform Resource Locator (URL)'. . . Who Governs the Internet?

The internet as a whole does not have a single controller.

Internet Corporation for Assigned Names and Numbers( ICANN) administers the domain name registration.
It helps to avoid a name which is already registered. . . What is W3C?
