The program tracks the path the network packets travel from your computer to the abusers'. The tracer resolves IP addresses and names for the routers along the way. With the help of advanced algorithms and extensive databases, the program also displays other valuable information for each hop of the trace, such as geographical position and ping time.

You can also trace the sender of an e-mail. The trace is performed the same way as described above. The difference is that you have an e-mail as input instead of an IP address.

Once the trace is finished a range of other tools can be used to find out a lot more information about the abuser. You can use the Whois tool, which can show you information about the IP address of the abuser.

Another available tool is the network scanner, which is really five different scanners. Scan results are displayed in two different ways simultaneously -- a tree view with expandable and collapsible nodes and a console displaying plain text output.

Another tool is the abuse reporter, which compiles and sends abuse report e-mails to the abusers' ISPs. The reporter can work totally automatic or ask for input and validation for each abuse report.

The last tool, the Netstat display, monitors your own computer's network adapters. You can use this tool to find out the IP address of any computer connected to you.
