Why isn't it possible to gain a delegation by proving number assignment?
Because your ISP can't be bothered. I have a free /48 from Hurricane and they delegated the rDNS as part of the setup so it's not like it's unusual or difficult. Delegating IPv6 rDNS is much easier than IPv4 because the delegation point is always between two labels in the rDNS, no funky CNAMEs needed. As you have noticed, you won't have much success sending mail from a host without rDNS. R's, John
