Route changes are relatively normal. They are sometimes hard to deal with by an application, though, so many traceroute applications just ignore the fact that the route could change.

This is what happens when you put NeoTrace into "Ping" mode - the first time you enter the target into NeoTrace, it does a trace route. Then, as it continues to collect data about these destinations, it pings every target it found the first time. This is a pretty standard method, but has several shortcomings, including that it doesn't understand route changes, so you often collect data about routers that aren't participating in getting packets from you to your destination (and/or back again). Basically, the first time pass it finds the route, but after the first pass, it doesn't check back to see what the route is again.

If you don't want to see information about the route changes in Ping Plotter, you can mask out those route changes. If you need help with this, please check out our tutorial (http://www.pingplotter.com/tutorial/) or send an email to support@pingplotter.com.
