The ISC license is a permissive free software license written by the Internet Systems Consortium (ISC). It is functionally equivalent to the 2-clause BSD license, with language "made unnecessary by the Berne convention" removed. Initially used for the ISC's own software releases, it has since become the preferred license of OpenBSD (starting June 2003), among other projects..
Before accepting the license as a free software license, the Free Software Foundation (FSF) asked for clarification of the text. As a result, in July 2007 "and distribute" was changed to "and/or distribute".
