Running a Trace Route

Keywords:

Trace routes can help identify where connection problems occur by testing the connection from your computer to a specified target location. A trace route report shows the step-by-step path that a packet of test data takes to reach its destination.

With the information from a trace route, you can work with your Internet Service Provider (ISP) to solve Internet connection issues. Follow the instructions below for your operating system.

Running a Trace Route

  1. Click Start and type CMD in the search field.
  2. Right-click on CMD.exe and select Run as Administrator.
  3. Type tracert xxx.xxx.xxx.xxx > c:\tracert.txt and press Enter. Replace the x's with the appropriate server address.
  4. Allow several minutes for the trace route to complete.
  5. A file will be created inside your C: drive called tracert.txt that contains your trace route information.
  6. Type exit and press Enter to close the command window.

Analyzing a Trace Route

If you notice any of the following problems in your trace route report, it may indicate an issue with your connection:

  • Time outs
  • * symbols
  • If the number value before the ms jumps from a low number to high number
  • If the numbers stay at high values.

Because of the safeguards that protect our Battle.net servers, you may notice later hops in your trace route failing with an error message such as 'Request Timed Out' or 'Destination Net Unreachable'. You may also see inflated latency numbers. You can ignore any error messages you receive after contacting our servers as they do not indicate a problem with your internet connection. To identify our servers, look for the following suffixes: attens.net, att.net, alter.net, telia.net.
