lowering maximum assignment window
by Paula Caslav 01 Mar '99

Hi all, Below is my original message with a proposal to lower the maximum assignment window to a /21 instead of a /19. There was much discussion about this on the lir-wg mailing list. Here is our final proposal that tries to take all the comments into consideration: All registries that currently have a /20 or /19 assignment window will be at a rotating interval (doing them all at once would put too much of a load on an already large wait queue) set to a /23 assignment window temporarily. They will then need to start sending a few requests to show that they understand the assignment policies and procedures. If these requests are fine, we will raise their assignment window to a size that matches the requests we have seen from them (therefore not necessarily to a /19). Hopefully this will get these registries on an equal footing with other LIRs. The reason we need to review the assignment window for all of these registries is that they started out with a /19 assignment window in the beginning of the RIPE NCC. Whereas younger registries started out with a 0 assignment window and have since then proven that they can handle assignents of a certain size and have therefore had their assignment window raised. For all of the younger registries we already have a procedure in place of doing random audits and we will continue doing this. By the way, one of the results of this discussion was that Poul-Henning Kamp wrote a script that checks for inconsistencies between addresses that are in use but are not registrered in the RIPE database. These statistics can be found at: http://stat.cybercity.dk/ripe/ Please check this page for your own registry ID to see whether your registry has any inconsistencies to fix. Of course the RIPE NCC will also be contacting the Registries with the largest list of inconsistenceis as well, but we don't have the resources to systematically contact every registry on the list.

Currently an assignment window for a Registry can be anything between a 0 and a /19. The /19 assignment window, is a historical legacy. These Registries were for the most part free to assign up to 8192 addresses to a customer without coming to the RIPE NCC for approval. Since some of them are still operating as Local Registries, and they still have a /19 assignment window, this means that we have very little contact with them and we have seen in doing audits on these Registries that many of them are out of date with the procedures for assigning IP addresses, and using the database. We also notice that most of them do not really use this large assignment window fully- meaning that most of their assignments are smaller. The router technology has changed much in the last few years, which means that assignments to customers in general are much smaller. Given the fact that most Registries rarely make such large assignments, and the fact that having such a large assignment window makes it easy for them to lose touch with the RIPE NCC policies, we would like to propose having a lower maximum assignment window. We think a /21 maximum assignment window would be more reasonable. Actually for most Registries, a /24 or /23 assignment window is enough, since they rarely make larger assignments than that. However, for the Registries that make more large customer assignments, having up to a /21 assignment window would allow them room to make most of these larger assignment without coming to us for approval. Please think about this proposal and give us any comments by the end of next week. Kind regards, Paula Caslav Registration Services Manager RIPE NCC ------- End of Forwarded Message
