An Internet Experiment Note (IEN) is a technical document used primarily in the early development and evolution of the Internet, particularly during the time when the ARPANET was transitioning to what we now know as the Internet. IENs were used to share experimental ideas, protocols, and implementations related to networking and the development of Internet standards. IENs often contained proposed methods, ongoing research, and contributions from various individuals and organizations working on the development of networking technologies.
