The Darknet is the part of the Internet used for anonymous communications. It is used for both good and evil. The Deep Web and Darknet are often confused, especially by the media. The Deep Web refers to anything that is not Google searchable. Estimates say that 96% of the data on the Internet is in the Deep Web.
You probably use the Deep Web every single day. The Deep Web is any data that is not indexed by search engines.
Darknet is part of the Deep Web, but a very small portion. The Deep Web consists of 96% of the data on the Internet, but Darknet is estimated to be less than 3% of the Deep Web. A news story stating 96% of the Internet is hidden sounds much more ominous than Darknet being 3%.
