For a router with a fixed IP address (like mine), that IP address
identifies me (or the small number of people with accounts on my machine).
For a leased IP, the combination of the IP and the time are equivalent to
a fixed IP. Just needs the cooperation of the ISP to decode it. But I
would expect the table of IP leased against time would be traffic data,
and hence demandable by TPTB (but not by any random Tom, Dick or Harry,
because the IP/time combination is surely Personal Data). Whether ISPs can
be forced to retain this data for some specified period I don't know, but
if such is not lawful at the moment, for sure it soon will be.
