The IAB is composed of twelve members selected by the IETF Nominations Committee, the IETF Chair (also selected by the IETF Nominations Committee), and several ex-officio and liaison positions.

The Internet Architecture Board (IAB) consists of thirteen members. Of these, six are nominated each year by a nominating committee drawn from the Internet Engineering Task Force (IETF) for a two year term. This process is described in RFC 8713. The thirteenth member of the IAB is the IETF Chair. The IAB elects its own Chair from among its twelve IETF-nominated members.
