Hi, I would like to get help for the following situation. I am at the Court with a guy who made several unauthorised access to my computer.

Now the Court approved a very strange expretize on his computer.

For this reason I am looking to found out if any computer is storing the history of it's public IPs were given to it through by his Internet Provider.

My opinion is that in the best situation is possible to find the last IP address, but not a history of 6-12 months back. To this computer was allocated Dynamic IP's by the provider.

I would like to underline that I am looking about the IP's were given ti that PC and not IP's of the searches made on it

I am also looking to find bibliography if it exist for this topic. 

 

Thank you,

Vasile

By default, the local machine doesn't keep a log of the IP addresses that it has been assigned.  It can be configured, but odds are that's not going to help in your situation.  Additionally if the machine was behind a router it would only have the private IP addresses that it was assigned, not the public IP address.  You would need to go through the person's Internet Service Provider (ISP) to find out what IP addresses they were assigned to their equipment.

DEar Kilroy, thank you for your answer. it helps me a lot

"By default, the local machine doesn't keep a log of the IP addresses that it has been assigned" - I am looking to find something to prove this at the Court. To prove the by default the machine doesn't keep the log of IP. I would be great if you can advice about bibliography for this. thank you

Check the thread I linked previously.  You'd have to search for a Microsoft link for what turning on DHCP logging would mean and that it is turned off by default.  As I said before this would only be of value if the person directly connected their machine to the Internet.  If they go through a router it would be worthless, even if turned on, as you would only receive information about the local network.  In order to get their public IP addresses over time you would need to obtain the information from their ISP.
