A DNS domain name is a mapping of, among other things, IP addresses to (ideally) human-readable words. Domain names are delegated through a hierarchy in the form delegate.principal.top. Domain names form the authority component of a URL, and from which root URLs to websites can be programmatically inferred, which causes some to say URL when they mean domain name.
