My question is regarding someone pirating a movie from a shared router. I work at a fire station with many people and we have received a letter that someone had pirated a movie from the shared router. I know the movie that was downloaded and the date it was downloaded. Is there a way to to use the router to find the history of ip addresses connected to it in the past at a certain date and time to find out who downloaded and when?

In the router interface, there's likely an screen or log file showing DHCP leases. This may  show an IP address , machine name and a MAC address. DHCP hands out IP addresses dynamically meaning they'll change over time. The problem is that the pirated movie likely was downloaded months ago. The computer that IP address was assigned to at that time has likely changed and assigned to a different computer now. If you can find a log for the download date/time and it contains a computer/device name that might give you a clue to who's computer downloaded the movie. If more than 1 person uses that computer/device, that complicates  finding the person that downloaded it. You might check online for the manual for your router.

"that someone had pirated a movie from the shared router"


Sounds like someone is stirring the proverbial pot. Much ado about nothing.


You don't pirate from a router.  You pirate by using software to download previously pirated software like movies through the router.


Your router won't contain logs that you can use and even then if there were logs you would need to know the mac address of the device that did the download.


You would need a more sophisticated system with a captive portal [that requires you logon before going to the internet = associated mac address with a person] and has logging.  Of course then you could also do domain filtering [with a subscription from the firewall provider] to block site access the department deems unacceptable to access from work [like porn]

As the courts have yet to understand, an IP address doesn't equate to an individual and your case shows that quite clearly.  Any information they would have is the public IP address of the router the addresses behind the router probably aren't logged or monitored, they aren't going to have the internal address that was used.


There is nothing you can do about this since the issue is in the past.  The best you can do is prevent it in the future by turning off UPnP on the router, or implement a logged routing solution.  Turning off UPnP would prevent people from running a server and sharing copyrighted information in the future, or at least make them use a different method.

It is possible that the IP address you have was previously assigned to someone else.
The ISP *might* have records about who that IP address was assigned to on the date of the download.

An IP address is generally kept by one provider. For example, I found documentation of an old IP address I had from Comcast.
That one is now assigned to a Comcast customer in Cleveland, Ohio.

I was somewhere in Alabama (Tuscaloosa) when I had the previous one and I still live Tuscaloosa, Alabama.
