Internet Architecture Board


IAB Statement on IPv6

The Internet Architecture Board (IAB), following discussions in the Internet Engineering Task Force (IETF), advises its partner Standards Development Organizations (SDOs) and organizations that the pool of unassigned IPv4 addresses has been exhausted, and as a result we are seeing an increase in both dual-stack (that is, both IPv4 and IPv6) and IPv6-only deployments, a trend that will only accelerate. Therefore, networking standards need to fully support IPv6. The IETF as well as other SDOs need to ensure that their standards do not assume IPv4.

The IAB expects that the IETF will stop requiring IPv4 compatibility in new or extended protocols. Future IETF protocol work will then optimize for and depend on IPv6.

Preparation for this transition requires ensuring that many different environments are capable of operating completely on IPv6 without being dependent on IPv4 [see RFC 6540].  We recommend that all networking standards assume the use of IPv6, and be written so they do not require IPv4. We recommend that existing standards be reviewed to ensure they will work with IPv6, and use IPv6 examples. Backward connectivity to IPv4, via dual-stack or a transition technology, will be needed for some time. The key issue for SDOs is to remove any obstacles in their standards which prevent or slow down the transition in different environments.

In addition, the IETF has found it useful to add IPv6 to its external resources (e.g., Web, mail) and to also run IPv6 on its conference network since this helps our participants and contributors and also sends the message that we are serious about IPv6. That approach might be applicable to other SDOs.

We encourage the industry to develop strategies for IPv6-only operation. We welcome reports of where gaps in standards remain, requiring further developments in IPv6 or other protocols. We are also ready to provide support or assistance in bridging those gaps.

Please comment on IAOC candidates for IAB selection

As described in BCP 101 (RFC 4071) and BCP 113 (RFC 4333), the IESG and the IAB each select one person for a two-year IAOC term in alternate years. This year, the IAB will select one person for a term beginning in March 2017.

Following the call for nominations, which ran from 5 October 2016  through 2 November 2016, the IAB contacted each person that was nominated, asking them to accept or reject their nomination.  At  this point, 7 people have indicated a willingness to serve. They are:

Charles Eckel
Nalini Elkins
Aaron Falk
Gaurav Meena
Abdelhamid AL Rahamneh
Kaveh Ranjbar
Gatta Sambasiva Rao

The IAB is actively soliciting confidential comments on these people and their ability to serve on the IAOC. The IAB needs to receive these comments by 30 November 2016 in order to make a selection in December 2016. Please send comments to and

Note that the NomCom will also be selecting a person to serve on the IAOC for a two-year term. This process is orthogonal, the IAB is not privy to comments you might have submitted to the NomCom.

The IAB is Seeking Feedback on the Independent Stream Editor (ISE)

As part of its oversight responsibility for the Independent Stream, the IAB is soliciting comments from the community on the performance of the Independent Stream Editor, Nevil Brownlee.  We are interested in comments on what has gone well or badly in the last several years of operation of the Independent Stream and Nevil’s activities as ISE.

Please send comments to iab-chair at  In addition, please CC execd at

We would appreciate receiving comments by Tuesday, November 29, 2016 as the IAB will likely begin the next steps in the oversight process shortly after the end of IETF 97 in Seoul.

IAB Seeks Feedback on Appointment to ICANN Technical Liaison Group

The IAB names two technical experts to the ICANN Technical Liaison Group (TLG). The TLG is tasked with connecting the ICANN Board with appropriate sources of technical advice on specific matters pertinent to ICANN’s activities.

Warren Kumari and Paul Wouters are the current experts. Paul’s current term ends in early 2017; he has indicated that he is willing to serve for an additional two-year term.

The IAB would like to solicit comments from the community on the performance of Paul Wouters on the ICANN TLG. Please send comments to iab-chair at and execd at

We would appreciate receiving comments by Wednesday, October 26.

Call for IAOC Nominations and Volunteers 2017

This is a call for nominations for the IAB appointment to the IETF Administrative Oversight Committee (IAOC). The nomination period will close on 2 November 2016.

IAOC membership is described in BCP 101 (RFC 4071) Section 4, with selection guidelines and process documented in BCP 113 (RFC 4333). In alternate years, the IESG and the IAB each select one person for a two-year IAOC term. This year, the IAB will select one person for a term beginning in March 2017. Note that the NomCom is also selecting an IAOC member.

Candidates for these IAOC positions should have knowledge of the IETF, knowledge of contracts and financial procedures, and familiarity with the administrative support needs of the IAB, the IESG, and the IETF standards process. Candidates are also expected to be able to understand the respective roles and responsibilities of the IETF and ISOC in this activity, and be able to articulate these roles within the IETF community.

Acceptable candidates must be prepared to exercise all the duties of an IAOC member. These responsibilities include, but are not limited to, the setting (in consultation with the community and after carefully considering their input) of administrative support policies, oversight of the administrative operations of the IETF, and representing the interests of the IETF to the IAOC. The IAOC meets for a couple of hours at each IETF meeting, holds two conference calls each month, and meets for two days in a separate meeting, usually in May. Acceptable candidates must be able to undertake full participation in all IAOC meetings and activities.

IAOC members also serve as the trustees of the IETF Trust. Please note that the role of the IETF Trust is expanding as part of the IANA stewardship transition.

The IAB-selected member of the IAOC does not directly represent the IAB. The IAB and IESG selected members are accountable directly to the IETF community. As such, candidates do not need to be current members of the IAB or the IESG and, in fact, we prefer nominations and volunteers from the rest of the community.

If you are interested in serving on the IAOC, or know of someone who may be a good fit for this position, please send the name and email address to <> and <>.

The IAB will respond with a questionnaire, asking for the candidates’ qualifications and willingness to serve.

The names of all people who declare themselves willing to serve will be made public on the list after the end of the solicitation period. The plan is to post the list of candidates by 4 November 2016.

The IAB expects to make a decision in December 2016.

IAB Seeks Feedback on IETF Appointment to the ICANN NomCom

The IAB (on behalf of the IETF) has been asked to supply a member to the 2017 ICANN Nominating Committee (NomCom). Last year, Tim Wicinski did the job for the IETF community, and he is willing to serve again.

The IAB would like to solicit comments from the community on the performance of Tim Wicinski on the ICANN NomCom. We are interested in comments on what has gone well or badly over the past year.

Please send comments to iab-chair at and execd at

We would appreciate receiving comments by Wednesday, September 28, as the IAB will begin the next steps in this appointment process shortly so that the ICANN NomCom member can attend the first formal meeting of the 2017 NomCom in Hyderabad, India in November 2016.

Allison Mankin to be next IRTF Chair

After having served as IRTF chair since 2011, Lars Eggert will step down as Internet Research Task Force (IRTF) chair during IETF 98 in March 2017.

The IAB has appointed Allison Mankin as his successor, and in the months to come Allison will be working with Lars in transitioning responsibilities.

Allison Mankin is an Internet protocol lead and researcher based in the Washington DC area, and holds the position of Senior Director, Public DNS, at Salesforce.  She has a long history in and around the IETF and IRTF, including serving as Nomcom Chair, Transport AD (most recently stepping down in 2006), and IPng AD.  In the IRTF, she chaired the Reliable Multicast RG and then moved it to the IETF as the RMT WG.  She has worked in a diverse set of industry, academic and government settings.  Some of her positions prior to Salesforce were at Verisign, JHU Applied Physics Lab, the US National Science Foundation (NSF), Bell Labs, and USC/ISI.  As a program director at the US NSF, Allison was a leader of the Future Internet Design (FIND) program, which initiated the funding of info-centric networking and also played an early role in software-defined networking.

The IAB would like to thank Lars for serving the community by fulfilling the role with zeal and thank Allison for taking up the responsibility.  The IAB would also like to thank the other volunteers for this position; with so many good candidates, it was a difficult choice for the IAB.
