The IETF Administration LLC (IETF LLC) provides the corporate legal home for the IETF, the Internet Architecture Board (IAB), and the Internet Research Task Force (IRTF).
The best possible support corporation to the IETF/IRTF/IAB
The IETF LLC has no role in the oversight or steering of the standards process as currently conducted by the IESG and IAB, the appeal chain, the confirming bodies for existing IETF and IAB appointments, the IRTF, or ISOC's memberships in other organizations.
The IETF LLC holds an annual strategic retreat to develop its annual strategic plan, which is then shared with the community for feedback before it is finalised:
The IETF LLC is a single member LLC disregarded entity of the Internet Society. It is a 501(c)(3) charity but does not have a separate IRS registration as a single member LLC disregarded entity and so any charitable contributions to the IETF are treated as contributions to the Internet Society, and the IETF LLC does not complete a Form 990 as it is included on the Form 990 of the Internet Society.
The IETF LLC implements the v2.0 IETF Administrative Support Activity (IASA), replacing the previous IETF Administrative Oversight Committee (IAOC) as documented in a set of RFCs produced by the IASA2 working group:
RFC 8711 Structure of the IETF Administrative Support Activity, version 2.0
RFC 8713 IAB, IESG, IETF Trust, and IETF LLC Selection, Confirmation, and Recall Process: Operation of the IETF Nominating and Recall Committees
RFC 8717 IETF Administrative Support Activity 2.0: Consolidated Updates to IETF Administrative Terminology
