Could someone explain why a DNSBL needs to return IPV6 addresses?
I don't know anyone who thinks that a DNSBL should return anything
other than A and TXT records. What leads you to believe otherwise?
A missunderstanding perhaps? There has been a lot of discussion in this
list about IPV6, after all. Is all this discussion about queries for the
status of the IPV6 equivalents of 127.0.0.X for testing if the DNSBL
covers IPV6 addresses? But aren't all IPV4 addresses expressible in IPV6
format? Won't those addresses do?
