In IPv6, encryption becomes “easily accessible and transparent to consumers”
What nonsense. IPv6 has no more security features than IPv4.
IPv6 designers in their wisdom mandated that IPv6-compliant devices must have IPSEC capability; but without a keying infrastructure (which doesn't exist) it will never be used except for manually-configured tunnels.
As for IPv6 address space: it's very easy to take the top 64 bits which locates you to an individual network. Plus: as time goes on, a single IPv4 addresses will end up being shared between multiple subscribers, thus making it more difficult to use an IP address to identify a miscreant (there will be more false leads).
Senior plod never really did understand technology very much.
