RIPA s2: "telecommunication system" means any system (including the apparatus comprised in it) which exists (whether wholly or partly in the United Kingdom or elsewhere) for the purpose of facilitating the transmission of communications by any means involving the use of electrical or electro-magnetic energy.

Does "system", which is not defined in the Act as far as I can see, limit it to physical objects (though I'd have thought the wording implied that there was more than just "apparatus" involved)?

Device continuing to listen to Ethernet using an expired IP address (or device listening to old response packets on a newly issued address) is covered anyway :(
