Traceroute
Trace the network path and measure hop-by-hop latency to any destination
Traceroute shows the path packets take through the internet by listing each router (hop) along the way and measuring response times. Unlike ping which only tests end-to-end connectivity, traceroute reveals the complete network path and identifies where delays or failures occur.
Network Traceroute
Enter a hostname or IP address to trace the network path. This tool helps diagnose network routing issues and identify bottlenecks that ping alone cannot detect.
About Traceroute
Traceroute is a network diagnostic tool that displays the path packets take from a source host to a destination host. It works by sending packets with incrementally increasing TTL (Time To Live) values. Each router decrements the TTL by 1 when forwarding packets, and when TTL reaches 0, the router returns a "time exceeded" message.
Primary Uses:
- Diagnose network connectivity issues
- Identify bottlenecks in network paths
- Analyze sources of network latency
- Verify network routing configuration
- Monitor network performance changes
Difference from Ping:
- Ping only tests end-to-end connectivity
- Traceroute shows the complete network path
- Traceroute can pinpoint where problems occur
- Traceroute provides latency info for each hop
Command Format & Usage:
Windows: tracert [options] destination
Linux/Mac: traceroute [options] destination
Common Options:
-h max_hops- Maximum number of hops-w timeout- Wait timeout per reply-q queries- Number of queries per hop
Examples:
tracert google.comtraceroute -h 15 8.8.8.8tracert -w 3000 cloudflare.com
How to Read Results:
Hop Number: Sequential router number in the path
Response Time: Round-trip time to reach that hop
* Symbol: Indicates no response (possibly blocked by firewall)
Usage Considerations
Limitations:
- Some routers may not respond to traceroute requests
- Firewalls may block ICMP or UDP packets
- Load balancing can cause inconsistent paths
- Network congestion affects measurement accuracy
Best Practices:
- Run multiple tests for more accurate results
- Test at different times of day
- Combine with ping tests for comprehensive analysis
- Pay attention to hops with unusually high latency
