Even if the OP is not obliged to reply wouldn't it be more prudent of him to reply explaining his situation as he has here rather than either just ignoring it or sending it back marked "Not known at this address"?
Seems to me the OP would be better off trying to nip this in the bud now by honestly explaining that someone must have given the police a false address rather than dealing from the hassle likely to result from not replying or marked "Not known".
My immediate reaction upon skimming your post was "This!"
Doesn't Andy Foster usually suggest it's better to lay your cards on the table earlier rather than later?
For the sake of completeness, firstly, SP is correct that the OP has no legal obligation to respond at all.
Secondly, what you said. Thirdly, if somebody has been taking liberties with the OP's address (whether specifically aimed at the OP, or more likely simply picked an address at random), there is a possibility that there is more to follow and both setting out one's stall early, and having a paper trail regarding same might avoid a lot of avoidable hassle further down the road.
In general, if the unfettered truth is not your friend, then it is generally prudent to play your cards as close to your chest as the law permits.
If you have a defence that relies on your credibility as a witness, setting out your stall early is generally a good idea.
If you have been improperly placed upon the sausage machine, heading it off at the pass may well save a lot of avoidable hassle later.
N.B. This is not a mixed metaphor (technically) as these are 3 separate statements.
@OP - Try to avoid making a somewhat spurious assumption and running with it.
The first point, is that you are not the person named, nor does he live at that address, nor (presumably) do you or anyone else living at that address have any know anyone of that name.
The notice (which is not addressed to you, and which you are not obliged to respond to, but might save avoidable hassle further down the road if you do) does not ask if you, anyone else at the address, or the person named on the notice has ever owned or registered a vehicle, it asks who was
driving. We do not know whether there was any chain leading to "your" NIP, or whether it was sent to the RK (as recorded by the DVLA), despite no V5C ever having been received.
What is most relevant is whether you (or anyone else at the address) was driving, or has any knowledge of who was driving, or has any connection to or knowledge of the vehicle in question.
Whether or not any of you own a car, has little to no bearing regarding the question of who was driving the vehicle in question.
