This means that as soon as it hits the first router in the path (within your network), it will timeout. It will first send 3 packets to an unreachable port on the target host, each with a Time-To-Live (TTL) value of 1. ![]() How does traceroute work?īy default, traceroute sends three packets of data to test each 'hop' (when a packet is passed between routers it is called a 'hop'). The stats from the entire test - the minimum time it took to reach the destination, the average, the maximum, and the standard deviation. This shows the results from each individual ping, with their round trip time in milliseconds.ĥ packets transmitted, 5 packets received, 0.0% packet loss ![]() If you can, great! If not, you can use traceroute to investigate what's happening at every step between your device and the destination. It's basically a quick, easy way to verify that you can reach a destination on the internet. It sends a request and waits for a reply (which it receives if the destination responds back within the timeout period). Ping uses ICMP (Internet Control Message Protocol) Echo messages to see if a remote host is active or inactive, how long a round trip message takes to reach the target host and return, and any packet loss. It's useful for tracing network problems, discovering where connections fail, and tracking down latency problems. Traceroute is a command you use to 'trace' the route that a packet takes when traveling to its destination. ![]() Ping is a simple command that can test the reachability of a device on the network. Ping and traceroute are common commands you can use to troubleshoot network problems.
