The IAB is in the process of making an appointment to the ICANN 2022 Nominating Committee.

In May, the new slate for the ISOC Board of Trustees was announced. The IAB, on behalf of the IETF, appointed Brian Haberman and Jon Peterson to the BOT back in March, but the appointment was not announced until the full BOT slate was available. The terms of office for all of the new Trustees will commence with the Internet Society board’s 2021 Annual General Meeting later this month.

IAB Open Meeting

During IETF 111, the IAB will hold an IAB Open Meeting on Thursday, July 29, 2021 at 23:30 UTC. The goal of this meeting is to increase interactions with the community in both directions: providing information about and reporting back on technical work done, as well as gathering input about on-going work.

Liaison statements are posted at

The IAB received three liaison statements since IETF 110:

The IAB liaison coordinators (Wes Hardaker and Tommy Pauly) have been reaching out to and holding conversations with all of the IAB appointed liaison managers to discuss each manager’s view of their position, time commitments, what information should be reported on a regular frequency to the IAB and the IETF, and how frequently the managers would like to have conversations with the liaison coordinators and/or the IAB.

Technical Programs and Support Groups

All active programs and groups are listed at and in the datatracker

As part of its effort to refine the IAB’s program structure into Technical Programs and Administrative Support Groups, the IAB is currently reviewing all open programs.

The Evolvability, Deployability, & Maintainability (EDM) Program was reviewed by the IAB on May 5, 2021. The EDM Program is currently reviewing draft-iab-use-it-or-lose-it and will further continue work on draft-iab-protocol-maintenance.

The Internet Threat Model (model-t) Program will be reviewed on August 11, 2021. Program members have produced a number of documents, but there hasn’t been much recent discussion and no document is currently up for adoption by the IAB.

The IETF-IANA Group was reorganised at the beginning of the year. This group meets once per meeting circle. Meeting minutes are included in the monthly IANA liaison report to the IAB.

The Technical Plenary Planning Program is on hold as long as the IETF meeting is online only.

The RFC Editor Future Development Program has adopted draft-iab-rfcefdp-rfced-model. This program works like an IETF working group and work is performed via email and frequent interim meetings.

Documents and IAB Statements

All documents the IAB has adopted and is working on can be found at

Since IETF 110, the IAB has published RFC 9075: Report from the IAB COVID-19 Network Impacts Workshop 2020.

In July, the IAB approved draft-iab-arpa-authoritative-servers-01 for publication as an Informational RFC on the IAB stream.

Also in July, the IAB posted an IAB Statement on Inclusive Language in IAB Stream Documents.

Workshops and Workshop reports

As mentioned above, the report from the virtual workshop the IAB held last November on COVID-19 Network Impacts was published as RFC 9075.

The IAB announced a call for papers for a virtual workshop on Measuring Network Quality for End-Users that will be held 14-16 September 2021. Submissions should be sent to by Monday, 2021-08-02.

Mailing lists

IAB-maintained mailing lists are listed at

Tommy Pauly and Jiankang Yao serve as the sergeants-at-arms for the mailing list. For program-specific lists, the program chairs act as moderators. The rfc-interest list is moderated by the Temporary RFC Series Project Manager. As for all mailing lists of the IETF, we also expect professional behavior on our mailing lists.

There were no new mailing lists created since IETF 110.
