Dear Colleagues, During the Address Policy WG session at RIPE 53, we were asked to provide statistics showing - how many of the requests to make a PA assignment involve discussion with the requester; and - how much discussion takes place in those requests. We have prepared a set of statistics showing the number of rounds of messages in a ticket. Please note that tickets often include messages that are not directly related to the specific request. For instance, when an LIR is eligible for an additional allocation discussion can also occur on how to register something in the database, or we may remind them about an unpaid invoice. We looked at all the tickets where we approved PA assignments of prefixes up to and including /21 during the last three complete months of July, August and September in 2006. This was a set of 1100 tickets. The attached graph illustrates: - 80% of requests are approved immediately, or following just one exchange - 15% are approved with just two or three messages being exchanged - 4% of tickets involve a significant amount of discussion These figures show that only a small fraction of LIRs need significant assistance with their decision making. We will be able to dedicate significantly more time to this small group of LIRs if the minimum Assignment Window is raised. I hope you find these data useful when considering my proposal.
