A darknet (or dark net) is an overlay network that can only be accessed with specific software, configurations, or authorization, often using non-standard communications protocols and ports. Two typical darknet types are friend-to-friend[1] networks (usually used for file sharing with a peer-to-peer connection)[2] and anonymity networks such as Tor via an anonymized series of connections.

The reciprocal term for an encrypted darknet is clearnet[3][4][5] or surface web when referring to search engine indexable content.[6]


Originally coined in the 1970s to designate networks which were isolated from ARPANET (which evolved into the Internet) for security purposes,[7] darknets were able to receive data from ARPANET but had addresses which did not appear in the network lists and would not answer pings or other inquiries.

The term gained public acceptance following publication of "The Darknet and the Future of Content Distribution",[8] a 2002 paper by Peter Biddle, Paul England, Marcus Peinado, and Bryan Willman, four employees of Microsoft who argued that the presence of the darknet was the primary hindrance to the development of workable DRM technologies and inevitability of copyright infringement.

Journalist J. D. Lasica in his 2005 book Darknet: Hollywood's War Against the Digital Generation describes the darknet's reach encompassing file sharing networks.[9] In 2014, journalist Jamie Bartlett in his book The Dark Net would use it as a term to describe a range of underground and emergent sub cultures, including social media racists, cam girls, self harm communities, darknet drug markets, cryptoanarchists and transhumanists.[10]

As of 2015, "The Darknet" is often used interchangeably with "The Dark Web" due to the quantity of hidden services on Tor's darknet. The term is often confusingly[11] used interchangeably with the The Deep Web due to how Tor historically could not be search indexed. Mixing uses of both of these terms has been described as inaccurate,[12] with some commentators recommending the terms be used in distinct fashions.[13][14]


Darknets in general may be used for various reasons, such as:


All darknets require specific software installed or network configurations made to access them, such as Tor which can be accessed via a customised browser from Vidalia, aka the Tor browser bundle or alternatively via a proxy server configured to perform the same function.
