How does it do this? Here it gets a bit trickier to explain succinctly, so stay with me! TTL For each hop on the way to the destination device, traceroute provides the data's Round-Trip Time (RTT) and, when possible, the name and IP address of the device. To get between these two points, data must travel - or "hop" - through a series of devices, such as routers or switches, and hosts. These tools all essentially do the same thing: map the route that data takes from a point in a network (e.g. Most platforms offer traceroute as a tool, such as TRACERT on Windows, or TRACEROUTE on Linux and Mac. In a future post I will give some tips for interpreting the results. In this post we'll look at how traceroute works and how to do a traceroute. Yet, despite this ease of use, there is a fairly good chance you will misinterpret its results if you do not know how it works. And, l ike ping, the beauty of traceroute lies in its simplicity: it's a tool that any user with access to a command prompt can run. While ping can tell you if there is a problem, traceroute can help point to where the problem is. Since we covered ping in a previous post, it makes sense that we now take a look at its slightly more capable cousin. Whether you are a network n00b or a veteran administrator, ping and traceroute are probably your first two ports of call when troubleshooting network and internet connectivity or latency issues. And so it is in the internet world with ping and traceroute. Some things fit so well together that it is almost impossible to separate them when talking or thinking about them.
