Internet Draft
An Internet Draft (I-D) is a document published by the Internet Engineering Task Force (IETF) containing preliminary technical specifications, results of networking-related research, or other technical information. Often, Internet Drafts are intended to be work-in-progress documents for work that is eventually to be published as a Request for Comments (RFC), perhaps leading to become an Internet Standard. It is considered inappropriate to rely on Internet Drafts for reference purposes. I-D citations should indicate the I-D is a work in progress.
