I don’t believe the proposal offers enough benefit to be worth what implementation would likely cost. First, I am sincerely hoping that CGN is an extremely temporary situation. I’m not sure it should be worth the effort to recode the registry to support it. Second, I’m wondering if there’s any real advantage to having this level of detail on residential subscribers that don’t even get full addresses, since we don’t really tend to have it for single-address subscribers now. IMHO, best to just let each ISP keep this information for themselves as the relevant contact for abuse and such is usually the ISP and not the residential user anyway. Owen
