ARIN is soliciting community input on a proposed experiment that will require the temporary use of space from 18.104.22.168/10, the IPv4 addresses reserved to facilitate IPv6 deployment. (see NRPM policy 4.10)
There has been much discussion on the NANOG mailing list about the usability / routability of prefixes longer than a /24. In order to try to provide some additional data on this topic, the RIPE NCC has requested a small block of address space from the reserved /10 in order to run the following experiment:
RIPE Routing Information System (RIS) plans to announce a few blocks of sizes /24 to /28 (no more then ten at a time) out of the 23.128/10. They will monitor how this address space propagates in BGP and its reachability.
This experiment will provide the global community with insight on whether prefixes longer than a /24 from 23.128/10 are useable and reachable on the global Internet.
A description of this experiment, as well as the results of this research, will be published on https://labs.ripe.net/ . Additionally, ARIN will provide a link to the RIPE Labs page, as well as the end date of this experiment in the public Whois record of this registration.
Do you support the use of this reserved space for this experiment or not, and why?

This consultation will remain open through 5:00 PM EDT on Monday, 1 September 2014.
