Report about that on Out-Law:

Individuals can be identified despite IP address sharing, BT says

The use of Internet Protocol (IP) address sharing technology will not 
prevent individuals from being identified as the perpetrators of illegal 
online activity, BT has claimed.09 May 2013

The internet service provider (ISP) has announced that it is currently 
piloting technology called Carrier-Grade Network Address Translation 
(CGNAT) that will see as many as nine different customers share the same 
IP address.

BT said it is trialling CGNAT in a bid to make the most efficient use of 
existing "IPv4 internet address", which are currently "running out", 
before new "IPv6 addresses become widely adopted". Doing so will enable 
fixed-line internet customers to stay connected, it said.

Data protection law specialist Kathryn Wynn of Pinsent Masons, the law 
firm behind, said that there were privacy implications to IP 
address sharing that BT, and other ISPs that want to conduct similar 
trials, would have to consider.
