Visual IP Trace lets you trace IP addresses and websites back to their origin or geographic location, giving you the power to stop hackers, verify customer addresses, and put an end to abusive practices. With Visual IP Trace, you'll be able to automatically generate an email to the ISP responsible for any given IP address or website, a valuable tool for reporting malfeasance without the administrative tedium!
Every trace that you perform using Visual IP Trace will yield a geographic location plotted visually on a world map. What's more, if you are experiencing unusual slowdown or hangups trying to reach your favorite website, you can use Visual IP Trace to see a graphical display of every hop along the route from your PC to the website, showing you node names, locations, and network information so that you can quickly see if there's a bottleneck!
