Tracert, short for “Trace Route”, is a command-line utility that helps in diagnosing network connectivity issues by displaying the route taken by data packets to reach a specific destination. It identifies each hop along the path and calculates the time it takes for the data packets to travel from one point to another. Tracert can be particularly useful in determining potential delays or interruptions in network communication.
Command Prompt
on your Windows computer or Terminal
on Linux or macOS.tracert
followed by the target destination, which can either be an IP address or a domain name. For example: tracert example.com
The output will show a list of hops in sequential order, with each line representing a single hop, its IP address, hostname, and the round-trip time (in milliseconds) for the data packets to reach that point.
When analyzing the results of a tracert command, consider the following:
However, note that some routers may be configured to discard or de-prioritize ICMP echo requests (the packets used by tracert) due to security reasons or traffic management, which might result in incomplete or inaccurate tracert results.
While tracert is a handy troubleshooting tool, it has some limitations:
For more advanced network troubleshooting and analysis, you may consider other tools such as:
ping
: To test basic connectivity and latency towards a specific host or IP address.nslookup
or dig
: To look up DNS records, diagnose DNS problems, or verify proper domain name resolution.mtr
(My Traceroute): Available on Linux and macOS, it combines the functionality of both “traceroute” and “ping,” providing real-time, continuous statistics on each hop’s performance.
