Dark web

The dark web is the World Wide Web content that exists on darknets (overlay networks) that use the Internet, but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the web not indexed by web search engines, although sometimes the term deep web is mistakenly used to refer specifically to the dark web. The darknets which constitute the dark web include small, friend-to-friend networks, as well as large, popular networks such as Tor, Hyphanet, I2P, and Riffle operated by public organizations and individuals. Users of the dark web refer to the regular web as clearnet due to its unencrypted nature. The Tor dark web or onionland uses the traffic anonymization technique of onion routing under the network's top-level domain suffix .onion.
