Template:Infobox software license The ISC licence is a permissive free software licence written by the Internet Systems Consortium (ISC). It is functionally equivalent to the 2-clause BSD licence, with language "made unnecessary by the Berne convention" removed. Initially used for the ISC's own software releases, it has since become the preferred licence of OpenBSD, among other projects.
Before accepting the licence as a free software licence, the Free Software Foundation (FSF) asked for clarification of the text. As a result, in July 2007 the first instance of the word and in the first sentence was changed to and/or.
