ARIN Mailing Lists

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.
