Darknets are distinct from other distributed peer-to-peer networks as sharing is anonymous (that is, IP addresses are not publicly shared), and therefore users can communicate with little fear of governmental or corporate interference.
For this reason, darknets are often associated with dissident political communications and illegal activities. More generally, the term "darknet" can be used to describe all non-commercial sites on the Internet, or to refer to all "underground" web communications and technologies, most commonly those associated with illegal activity or dissent.
Originally coined in the 1970s to designate networks which were isolated from ARPANET (which evolved into the Internet) for security purposes, 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", a 2002 paper by Peter Biddle, Paul England, Marcus Peinado, and Bryan Willman, four employees of Microsoft who described the concept as follows:
The idea of the darknet is based upon three assumptions:
- Any widely distributed object will be available to a fraction of users in a form that permits copying.
- Users will copy objects if it is possible and if they are interested in doing so.
- Users are connected by high-bandwidth channels.
The darknet is the distribution network that emerges from the injection of objects according to assumption 1 and the distribution of those objects according to assumptions 2 and 3.
The Microsoft researchers argued that the presence of the darknet was the primary hindrance to the development of workable DRM technologies.
The darknet may be used for various reasons, such as:
- Out of privacy concerns or for fear of political reprisal
- To publish for criminal gain
- To share media files that are copyrighted.
When used to describe a file sharing network, the term darknet is often used as a synonym for "friend-to-friend"—both describing networks where direct connections are only established between trusted friends. The most widespread "non-darknet" file sharing networks, such as BitTorrent, are not true darknets since peers will communicate with anyone else on the network.
Almost all known darknets are decentralized and therefore considered peer to peer.
Many darknets require a software to be installed to access them.
- Private P2P
- Internet privacy
- Virtual private network (VPN)
- Freenet runs as a darknet (friend-to-friend) by default, from version 0.7 it can run as a "opennet" (connecting to untrusted users)
- GNUnet can run as a darknet if "F2F (network) topology" option is enabled
- Retroshare run as a darknet (friend-to-friend) by default to perform anonymous file transfers if DHT and Discovery features are disabled
- Syndie is software to publish distributed forums over several networks, including darknets and anonymous networks like I2P and Tor.
