Internet Architecture Board


About the Internet Architecture Board

The Internet Architecture Board provides long-range technical direction for Internet development, ensuring the Internet continues to grow and evolve as a platform for global communication and innovation.

In its work, the IAB strives to:

  • Ensure that the Internet is a trusted medium of communication that provides a solid technical foundation for privacy and security, especially in light of pervasive surveillance,
  • Establish the technical direction for an Internet that will enable billions more people to connect, support the vision for an Internet of Things, and allow mobile networks to flourish, while keeping the core capabilities that have been a foundation of the Internet’s success, and
  • Promote the technical evolution of an open Internet without special controls, especially those which hinder trust in the network.

RFC 8170 on Planning for Protocol Adoption and Subsequent Transitions

The IAB has published RFC 8170: Planning for Protocol Adoption and Subsequent Transitions.

Abstract: Over the many years since the introduction of the Internet Protocol, we have seen a number of transitions throughout the protocol stack, such as deploying a new protocol, or updating or replacing an existing protocol.  Many protocols and technologies were not designed to enable smooth transition to alternatives or to easily deploy extensions; thus, some transitions, such as the introduction of IPv6, have been difficult.  This document attempts to summarize some basic principles to enable future transitions, and it also summarizes what makes for a good transition plan.

RFC 8153 on Digital Preservation Considerations for the RFC Series

The IAB has published RFC 8153: Digital Preservation Considerations.

Abstract: The RFC Editor is both the publisher and the archivist for the RFC Series.  This document applies specifically to the archivist role of the RFC Editor.  It provides guidance on when and how to preserve RFCs and describes the tools required to view or re-create RFCs as necessary.  This document also highlights gaps in the current process and suggests compromises to balance cost with best practice.

Reappointment of Sean Turner to the Internet Society Board of Trustees

As set out in RFC 3677, the IAB is responsible for selecting a certain number of the Trustees who serve on the Board of the Internet Society.

In fulfillment of that responsibility, the IAB is happy to announce that Sean Turner has been selected for a second three-year term, to begin at ISOC’s annual general meeting in June.

The IAB had a very strong set of candidates this year, and we would like to express our appreciation to each of them for their willingness to serve.  We look forward to their continued engagement with the Internet Society and the IETF.

IAB Seeks Candidates for Community Coordination Group (CCG)

On behalf of the IETF, the IAB has been asked to name three representatives to the Community Coordination Group (CCG), which provides advice and guidance to the IETF Trust in matters related to the IANA trademarks and the IANA domain names. The process for appointing these representatives is outlined in RFC 8090.

The IAB is asking the community for volunteers to serve on the CCG. One person will be appointed for a one-year renewable term and two people will be appointed for two-year renewable terms.  If you are interested, please send a short email message to iab-chair at with a copy to execd at with you background and qualifications for the position. Note that Trustees of the IETF Trust are not eligible for this nomination. The deadline for nominations is Monday, 8 May 2017.

The IAB will select from the available candidates, taking into account the familiarity with IANA and the IETF, their roles, and the IETF protocols. The selected candidates will serve on the CCG on personal  title; however, the IAB will be looking for candidates who have an understanding of the interests of the technical community.

If you are willing to be considered or would like to nominate someone else for one of the CCG positions, please send an email message to iab-chair at and execd at by 8 May 2017.
