Ping Plotter Freeware runs on Microsoft Windows 98, ME, NT4, 2000, XP, 2003, Vista, 2008 and Windows 7. It features a multi-threaded trace engine and performs IP address to name lookups in a separate thread from traces. And if a route changes during a specific trace, Ping Plotter tracks the current route. The software’s graphical display shows route, hosts, packet loss percentage and latencies, and minimum and maximum response times for a range. Standard and Pro versions are also available for a charge.
