Internet Drafts (IDs) are a series of documents published by the IETF. They are drafts for RFCs. They have a validity of only 6 months, after which the IETF deletes them, although expired IDs can be found on a number of sites around the Internet.
They are given names of the following format: draft-<author>-<name>-<sequence number 00, 01, etc>.txt
This site is a good archive of IDs: http://www.watersprings.org/pub/id/
An Internet standard is a specification for an innovative internetworking technology or methodology, which the Internet Engineering Task Force (IETF) ratified as an open standard after the innovation underwent peer review.
An Internet standard begins as an InternetDraft, which may then be published (usually after several revisions) as a Request for Comments (RFC) memorandum.
An Internet standard, which may simply be referred to as a standard, is characterized by a high degree of technical maturity and by a generally held belief that the specified protocol or service provides significant benefit to the Internet community.
