Dark web
part of the World Wide Web that is not directly reachable from the public Internet
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.
Terminology
Definition
The dark web has often been confused with the deep web, the parts of the web not indexed (searchable) by search engines. The term dark web first emerged in 2009; however, it is unknown when the actual dark web first emerged. Many internet users only use the surface web, data that can be accessed by a typical web browser. The dark web forms a small part of the deep web, but requires custom software in order to access its content.
The public source identifies “Dark web” as part of the World Wide Web that is not directly reachable from the public Internet. This brief keeps that definition visible, then builds a research path around Dark, part and World.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Dark web”, the useful work is to connect “part of the World Wide Web that is not directly reachable from the public Internet” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q4120082. The Library of Congress control number is sh2018002121. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2009.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
