No search engines do not search the entire internet. The Internet encompasses much more than just the World Wide Web, the linked pages people typically surf and the portion plumbed by search engines. File-sharing sites, corporate data banks, government “intranets,” workplace servers, and other private sites are strictly off-limits to public snooping. And then there’s the murky region known as “dark net.” Uncharted by search engines, it’s the Internet’s seedy underbelly, home to anonymous users and secret networks that want to stay that way.
