Re: So they want..
"I wonder if this is more the case they cannot be bothered, or do not have the knowledge to make their network IPv6 friendly? Thus unable to "hack" or "track" remote IPv6-only hosts."
My first thought was this as well. A not small number of network admins have had a hard time with wrapping their heads around IPv6 as it is....and law enforcement/courts are just getting a solid mastery on IPv4. They will be a decade behind again if they have to start over learning 6.
