What Is Traceroute?
Traceroute is a network diagnostic technique used to display the sequence of routers, or hops, that traffic passes through while travelling toward a destination.
Each line in a traceroute normally represents one network hop. The reported response time helps show approximately how long that hop took to answer the probe.
What Does a Hop Mean?
A hop normally represents a router or network gateway between the source server and destination. Internet traffic can pass through multiple networks before reaching the final server.
Why Do Some Hops Show a Timeout?
A timeout does not necessarily mean that the route is broken. Some routers intentionally do not respond to traceroute probes even though they continue forwarding normal network traffic.
