> If they do have a port, then LEA can have a single subscriber.

Reading the original article (linked below) I am left with the feeling
that the problem is that they generally *don't* know the source port,
and therefore end up, quote, «[unable] to identify internet subscribers
on the basis of an IP address».

https://www.europol.europa.eu/newsroom/news/are-you-sharing-same-ip-address-criminal-law-enforcement-call-for-end-of-carrier-grade-nat-cgn-to-increase-accountability-online

The article proceeds to define «CGN» as «technologies which allow
sharing of IPv4 addresses with multiple internet users». In that
context, MAP, even though it is not technically CGNAT, is just as
problematic (to answer Rajiv).

C'est la vie! If Europol don't like IP address sharing, I think the
only thing they actually could do about it would be to put pressure on
regulators and/or lawmakers to accelerate IPv6 adoption. I understand
that's what already happened in Belgium with impressive results.
