To me this is really simple: If many/most ISPs continue *not* adding useless/artificial/synthesized PTRs, the content / server people will have no choice - if they want their content to get out and their services to be used by the large majority of IPv6 users, they'll have to accept connections from IPv6 addresses without PTRs. > I would still like to see: > > - actual data on how/where PTRs are being used and abused now (beyond > the known mail filtering) to see if any of those folks are planning > on continuing the bad idea into v6 Speaking only for myself: We're not planning to add useless IPv6 PTRs.
