There are two types of ARIN Members: General Members and Trustee Members.

General Members

General members are entities that have a valid ARIN Registration Services Agreement (RSA or LRSA) for Internet number resources and are enrolled in ARIN’s Registration Services Plan or pay an annual membership fee. General members fall into two categories:

Automatic Members

The vast majority of ARIN Members are Internet Service Providers (ISPs) that are automatically enrolled in ARIN’s Registration Services Plan and receive membership at no additional cost after receiving an initial direct allocation of IPv4 or IPv6 addresses.

ARIN Membership via Application

Entities with a signed LRSA / RSA and Internet number resources from ARIN (end users, for example) may become members by filling out the application and paying an annual $500 membership fee or requesting to enroll in ARIN’s Registration Services Plan.

For instructions on the application, please see the Applying for Membership via Application section of the ARIN Membership page.

Trustee Members

Trustee Members are comprised of the individuals elected or appointed to the ARIN Board of Trustees and the President and CEO of ARIN. Trustees are members during their tenure on the Board.

Member Responsibilities

As a service organization, ARIN places a premium on being responsive to the needs of the community. Our ability to respond is heavily impacted by the level of community participation in elections, meetings, and the policy process.

As the ARIN community grows and changes, we are actively seeking to diversify community involvement through our outreach and education activities. We rely on our members to be “good citizens” by voting in elections, attending meetings, and participating in the policy process, so we can continue to fulfill our mission.

Since voting in elections is one of the most important benefits of membership, this means that designating a Voting Contact and keeping that information up-to-date is a crucial responsibility of each ARIN Member. Without updated Voting Contact information, a member organization loses the ability to vote in annual ARIN Elections, which shape the future of our community and the Internet itself.
