Organizational structure
ARIN consists of the Internet community within its region, its members, a 7-member Board of Trustees, a 15-member Advisory Council, and a professional staff of about 50. The board of trustees and Advisory Council are elected by ARIN members for three-year terms.
Board of Trustees
The ARIN membership elects the Board of Trustees (BoT), which has ultimate responsibility for the business affairs and financial health of ARIN, and manages ARIN's operations in a manner consistent with the guidance received from the Advisory Council and the goals set by the registry's members. The BoT is responsible for determining the disposition of all revenues received to ensure all services are provided in an equitable manner. The BoT ratifies proposals generated from the membership and submitted through the Advisory Council. Executive decisions are carried out following approval by the BoT. The BoT consists of 7 members consisting of a President and CEO, a chairman, a Treasurer, and others.
Advisory Council
In addition to the BoT, ARIN has an advisory council that advises ARIN and the BoT on IP address allocation policy and related matters. Adhering to the procedures in the Internet Resource Policy Evaluation Process, the advisory council forwards consensus-based policy proposals to the BoT for ratification. The advisory council consists of 15 elected members consisting of a Chair, Vice Chair, and others.
