Well, in IPv4...  NAT broke it, because  networks implementing 1:many
NAT could no longer easily identify what host was responsible for
abuse.

What do you mean by suggesting IPv4 abuse management
techniques to map whose doing what, where do not scale  to
IPv6's larger address space?

There's no reason you can't provide accurate WHOIS
information with the larger address space..
