Tracing IP Addresses

[Mitch D]

I just got home to find an email (well several) from my router telling me that someone/something has been hitting my firewall regularly since about 1930 hours. What I would like to know is there a way to trace back a IP address to find the website, ISP etc where the attempt originated from?

In reviewing the log the same five or six IP's keep coming up...

Use the command "whois <ip address>" (with no quotes and brackets) and it will tell you all that information.

Windows does not have whois command by default. You may try an online whois database:

Thanks for the replys, I checked out serveral of the ip addresses hitting my firewall only one of which seem legit. I forwarded a copy of my log my to ISP to let them look into it further.
