Many people and organisations do not host their own websites directly, but
instead use a variety of third-parties to provide their website and associated
services. One common technique for high-volume websites is to use a Content Delivery
Network (CDN). Also, the site report may list companies such as hosting providers,
domain registrars, the Internet Service Provider (ISP) that provides the IP address,
and more. Most, if not all, of this information can be found in publicly available
sources.
