- How many network hops to resolve this domain?
- How is this system connected to the Internet?
A traceroute gives you a detailed log of all the network hops between your users (a monitoring node) and your target system. Traceroutes show you each sequential hop and the RTT (round trip time) for each successful hop. You can use traceroutes to quickly identify the source(s) of latency.
How It Works
Traceroutes are used to track transit delays of packets across a network. Rather than a ping which tells you the total RTT between a user and a system.
A traceroute will fail if two of the three packets sent are lost. This likely means that there is a faulty configuration somewhere.
Here, we have a simple traceroute for a website that goes from my computer to my ISP, to the CDN, and finally the web server for that website.
You’ll notice there is a really long wait between the third and second to last hop. I would want to find out what that IP is for (most likely my CDN) and find out why there is so much latency.
