I’ll swear it’s a horrible assumption. Personally, I use many IP addresses each day. Some of them are also used by others. Some of them are not. Equating IP Address <-> Person relationships as being anything remotely resembling 1:1 is beyond absurd. To do so with an IPv6 /64 is even more so. Considering it to be reasonable or “good enough” is so far from valid I don’t even know where to begin. Owen
