Dear colleagues of the Address Policy Working Group,

During (my first!) RIPE85 there was short discussion about the minimal size for IPv4 temporary assignments in this workgroup.

The policy for temporary IPv4 assignments requires you to use 50% of the assigned addresses [1].

This requirement pushes events or experiments into smaller assignments less than /24’s, which are mostly unroutable on the internet.

This is mentioned before by Marco Schmidt [2] in October 2022 and Randy Bush [3] in Januari 2022.

It looks to me this is a legitimate reason to propose this in a policy change:

Temporary IPv4 assignments ≤ /24 should NOT subject to the 50% usage requirement;
Only smaller assignments will be handed out if the assignee is explicitly willing to have (sub optimal) unroutable IP space on the internet;
If it is required by the assignee to advertise multiple subnets, the policy should allow to assign multiple /24’s( or a bigger assignment, so the assignee can split and advertise by themselves).

Elvis Velea and myself are willing to (co) author this proposal. We will do our best to hand in the proposal by the end of this year.

Any thoughts on this?

Kind regards,

Edwin Verheul
