Jørgen, you raise an interesting question. This subject is certainly something for the WG to consider. How about presenting something at the next RIPE meeting? My personal opinion is that a mandatory policy is likely to be too cumbersome. It could also be painful for ISPs and the NCC: creating inetnum objects for every /29 or whatever an ISP gives to its DSL customers. That might also open the door to other complications. If some DSL user is in the NCC database because of an inetnum object for reverse delegation, maybe that user should be paying NCC fees? And does that user become responsible for maintaining that inetnum and related objects in the database? I've also got a gut feel that reverse delegation is really an issue between an ISP and its customer. If some ISP won't do reverse delegation properly (or at all), the customer is free to pick another ISP that does. Economic Darwinism should sort this out, just like it eliminates the clueless ISPs with lousy service. A document advising about reverse delegations which customers can put in front of their ISP would be no bad thing though. That said, I would welcome a discussion about the subject and encourage the WG, especially those at DSL providers, to speak up. I would also be pleased for the WG to produce some document on reverse delegation and strongly recommends this gets done properly. Making reverse delegation mandatory for all customer IP addresses may be a step too far IMO, but let the WG decide this. Perhaps you could start the ball rolling by preparing an initial draft with a view to starting a work item? I'm a great believer in delegation (excuse the pun), so over to you.... and the WG.
