It's about CGN use, which occurs both in IPv4/IPv4 and as used to provide 
IPv4/IPv6 compatibility.  From the document, " The solution described in 
this document is applicable to Carrier Grade NAT transition technologies 
(e.g. NAT444, DS-Lite, and NAT64)."

Sorry, perhaps I was unclear...  The referenced cases involve CGN devices 
with insufficient logging to allow accountability for involved messages.  
CGN use is going to increase in many cases because of particular service
provider architectures.

The appendix is interesting, but doesn't address the issue that presently 
there is no convention for necessary routine recording of dynamic address
assignment (a very different topic from interception), nor discussion of
appropriate norms for protection of access for such information.
