ARIN Mailing Lists
Mailing List Description Options
ARIN Discuss

Open to ARIN members, employees of ARIN member organizations, ARIN Board of Trustees, and ARIN Advisory Council members. RIR Staff members may observe, but not participate, in discussions.

Provides a forum for the member community to discuss ARIN-specific issues such as fee structures and internal policies.

ARIN Announce

Read-only list open to the general public. Used by ARIN staff to provide timely information on important issues affecting ARIN members and the Internet community. The issues include ARIN elections, meetings, policy updates, training opportunities, and other ARIN events. We encourage anyone with an interest in Internet operations in the ARIN region to subscribe.

Public Policy
Mailing List

Open to the general public. Provides a forum to raise and discuss policy-related ideas and issues surrounding existing and proposed ARIN policies. The PPML list is an intrinsic part of ARIN's Policy Development Process, which details how proposed policies are handled.

Discussion on PPML can cover a variety of policy related topics, and ARIN encourages free discussion. ARIN announcements to the PPML about policy proposals or draft policies include the proposal number or draft policy number in the subject field. Please retain the policy number in the subject line when you make comments about specific proposals or draft policies. Your post or reply should open with a statement of support or nonsupport for the topic to allow others to follow discussions of interest more easily and make your position clear.

IANA Transition

Open to the general public. This forum is to facilitate the discussion of the developing IANA Stewardship Transition planning process. ARIN is seeking community feedback regarding the future oversight of the IANA functions.

ARIN Issued

Read-only list open to the general public. It is a daily report of IPv4, IPv6, and Autonomous System Number (ASN) resources issued directly by ARIN, and resources returned to ARIN's free pool.
