The mail I'm replying to has as the first Received: line:

Obviously BCP38 doesn't help, as it's an established TCP connection so it can't be
spoofed traffic (gotta ACK  Google's ISN from the SYN-ACK)  - unless Google is silly
enough to *still* not be doing RFC1948 properly.  I mean, Steve Bellovin wrote
that literally last century. ;)

So - who owns 2800:af:ba30:e8cf:4881:973a:c68?  And how does an LEO
find that info quickly if they need to figure out who to hand a warrant to?

*THAT* is the problem that needs solving.

(And who *does* own that IP?   I admit not knowing. ;)
