tracert is a tool in Windows for diagnosing network connectivity issues, helping to identify delays, timeouts, or routing issues by showing every hop the data passes from the computer to the target server. 1. Open the command prompt: Press Win R, enter cmd and press Enter. 2. Perform basic tracking: Enter tracert google.com (replace the target with the desired URL or IP). 3. Interpretation result: Each hop shows three response times, high latency may indicate congestion, asterisks (*) indicate no response, which may be firewall shielding or device failure. 4. Use optional parameters: -d skip host name resolution, -h sets the maximum number of hops, and -w increases the timeout time. 5. Practical application scenarios include detecting website inaccessibility, locating network delay points, assisting technical support to troubleshoot problems, and can be used in combination with ping commands. 6. Note limitations: ICMP packages may be filtered, paths are not fixed, load balancing and NAT may affect accuracy, but tracert is still a fast and effective preliminary diagnostic tool.

The tracert (Trace Route) command in Windows is a powerful tool for diagnosis network connectivity issues. It helps you identify the path your data takes from your computer to a destination server, showing each hop (router or gateway) along the way. This can be useful for spotting delays, timeouts, or routing problems on the internet or within your local network.

Here's how to use tracert effectively:

1. Open Command Prompt

To run tracert , you need to open the Command Prompt:

• Press Win R , type cmd , and press Enter.
• Or search for "Command Prompt" in the Start menu.

You don't need administrator privileges for basic tracing, but it's safe to run it either way.

2. Run a Basic Tracert

Type the following command and press Enter:

 tracert google.com

Replace google.com with any website or IP address you want to trace.

What you'll see:

• A list of hops (routers) between your PC and the destination.
• For each hop, you'll typically see:
  • Hop number
  • Response times (in million seconds) from three separate probes
  • IP address (and sometimes hostname) of the router

Example output:

 1 1 ms 1 ms 1 ms 192.168.1.1
2 10 ms 9 ms 11 ms 10.10.0.1
3 25 ms 24 ms 26 ms 203.0.113.45
...

3. Interpreting the Results

Understanding the output helps pinpoint where problems occur:

• High latency (slow response times): If one hop shows a big jump in response time (eg, from 20ms to 300ms), that could indicate network congestion or a slow link.
• * Asterisks (` `):** These mean no response was received from that hop. It might be due to:
  • A firewall blocking ICMP packets (common with some routers)
  • A downed or unreachable device
  • Packet loss
• Consistent timeouts after a certain point: Suggests a routing issue or outage beyond that hop.

Note: Some routers are configured not to respond to traceroute requests for security reasons, so missing responses don't always mean a problem.

4. Useful Tracert Options

While tracert has fewer options than Linux's traceroute , here are a few helpful switches:

• -d – Skip hostname resolution

   tracert -d google.com

  Speeds up the trace by not trying to resolve IP addresses to hostnames.

• -h – Set maximum hops

   tracert -h 20 google.com

  Limits the number of hops before stopping (default is 30). Useful if the trace takes too long.

• -w – Set timeout (in million seconds)

   tracert -w 5000 google.com

  Increases the wait time per reply (default is 4 seconds). Helps if the network is slow.

  5. Practical Use Cases

  Here are common scenarios where tracert helps:

  • Website not loading? Run tracert to see if the connection fails at a specific hop.
  • Slow internet? Identify where latency spikes occur—within your ISP or farther out.
  • Troubleshooting with support: Provide a tracert output to your ISP or IT department to help them diagnose routing issues.

  Tip: Combine tracert with ping . If ping shows packet loss, use tracert to find where the loss starts.

  6. Limitations to Keep in Mind

  • Uses ICMP packets, which some networks filter or deprioritize.
  • Results show one path; internet traffic may take different routes at different times.
  • Doesn't work well with some modern networks using load balancing or NAT.

  Using tracert won't fix network issues directly, but it gives you insight into where the problem might be—your router, your ISP, or somewhere on the internet. It's a quick, built-in tool that's great for basic diagnostics.

  Basically, if you're having trouble reaching a website or service, tracert is one of the first things to try.
