v_trace vs Simply: Countdown使用状況と統計

v_trace is a visual traceroute application that shows* a list of the network servers from your machine to a target ip address or hostname and it attempts to place each to their corresponding location on a map. The map display consists of a pin for each hop, the color of the pins change from green to red reflecting the latency of the hop. *The ability to show and determine hops depends on your network's routing policies, if the packets are filtered no hops can be determined.
