So RIPE and Afrinic didn't coordinate transfer of the netblock properly. I don't see how this relates to the publication or otherwise of a draft which encourages DNS admins to provide PTR records. > 213.136.96.104 There is a delegation but no PTR So, we seem to have an ISP in Cote d'Ivoire that hasn't bothered with international best practice. Maybe publishing an RFC that recommends that they do, in fact, provide PTR records, will help this situation. It might mean that the responsible individuals can become aware of the issue, and justify to management why they should spend effort on what otherwise can seem an unnecessary frill. Prior to the establishment of Afrinic, large amounts of address space was delegated to ISPs and organisations all over Africa, and PTR records were set up for these as a matter of course. Some other African organisations chose not to provide PTR records. However, I don't see why we should accept poor operational practice and use it to justify why we should not publish a document that intends to help the situation. In fact, your arguments seem to completely support publication of the draft. If people are already blackholing based on lack of PTR mapping (which clearly they are), then publishing a document 1) encouraging people to provide these mappings, and 2) discouraging the practice of filtering based on non-availability of PTR records, both seem to be highly sensible.
