Which is why the tailpiece [1] on RIPA s21(6) seeks to restrict the 
definition of traffic data to *just* the "hostname bit". (Simplifying 
somewhat).

[1] "but that expression {traffic data} includes data identifying a 
computer file or computer program access to which is obtained, or which 
is run, by means of the communication TO THE EXTENT ONLY that the file 
or program is identified by reference to the apparatus in which it is 
stored." {my emphasis}.
