Answer
The IETF, Internet Engineering Task Force, is a loosely self-organized group of people who contribute to the engineering and evolution of Internet technologies. It is the principal body engaged in the development of new Internet standard specifications. The IETF is made up of volunteers, many of whom meet three times a year to fulfill the IETF mission.
There is no membership in the IETF. Anyone may register for and attend any meeting. The closest thing there is to being an IETF member is being on the IETF or Working Group mailing lists. This is where the best information about current IETF activities and focus can be found.
Of course, no organization can be as successful as the IETF is without having some sort of structure. In the IETF’s case, that structure is provided by other organizations, as described in BCP 11 (RFC-2028).
