Running a Trace Route or Pathping

Keywords: path ping, pathping, trace route, traceroute
We will occasionally request that a player send us a Trace Route or a Pathping so that we are better able to diagose connection or latency issues. Select the test you'd like to perform from the dropdown and follow the steps provided.

Pathping

A pathping is a tool used to check for losses of network packet integrity between your computer and our servers. Running a pathping is a great way to discover connection issues that may not show up in other latency tests.

  1. Click Start. Windows 8® users start on step 2.
  2. In the search field, type CMD.
  3. Right-click on CMD.exe and select Run as Administrator.
  4. Type pathping xxx.xxx.xxx.xxx > c:\pathping.txt
  5. Replace the Xs with the appropriate server address. Use all IP addresses listed for your region.
  6. Press Enter.
  7. Allow several minutes for the pathping to complete.
  8. A file will be created in your C: drive called pathping.txt.
  9. Type exit and press Enter to close the command window.

Trace Route

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.

  1. Click Start. Windows 8® users start on step 2.
  2. In the search field, type CMD.
  3. Right-click on CMD.exe and select Run as Administrator.
  4. Type tracert xxx.xxx.xxx.xxx > c:\tracert.txt and press Enter. Replace the x's with the appropriate server address. Use all IP addresses listed for your region.
  5. Allow several minutes for the trace route to complete.
  6. A file will be created inside your C: drive called tracert.txt that contains your trace route information.
  7. Type exit and press Enter to close the command window.

Pathping

A pathping is a tool used to check for losses of network packet integrity between your computer and our servers. Running a pathping is a great way to discover connection issues that may not show up in other latency tests.

  1. Go to the /Applications/Utilities folder and start the Terminal application.
  2. Type traceroute -S -q 30 xxx.xxx.xxx.xxx > ~/Desktop/pathping.txt
  3. Replace the Xs with the appropriate server address. Use all IP addresses listed for your region.
  4. Press Return. A file will be created on your Desktop called pathping.txt.
  5. Quit the Terminal application.

Trace Route

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.

  1. Go to the /Applications/Utilities folder and start the Terminal application.
  2. Type traceroute xxx.xxx.xxx.xxx > ~/Desktop/tracert.txt and press Return. Replace the x's with the appropriate server address. Use all IP addresses listed for your region.
  3. Allow several minutes for the trace route to complete.
  4. A file will be created on your desktop called tracert.txt that contains your trace route information.
  5. Type exit and press Return to close the terminal.

Analyzing my Pathping

Look at the second block of data with the percentages. A clean pathping will have nothing but 0% from your computer to the last hop before our servers. Anything other than 0% indicates loss of packet integrity.

Our servers scramble pathping data once it reaches them. You can disregard any data which typically shows as 100% packet loss once the pathping reaches that point. To identify our servers, look for the following suffixes: attens.net, att.net, alter.net, telia.net.

If there is consistent packet loss of 1% or more at your router (hop 0) or modem (hop 1) these components either need a firmware update or need to be replaced. Packet loss anywhere else along the route should be reported to your ISP. Making a post of your pathping data on our tech forums will alert us of the ISP issue as well, and is much appreciated.

Here is a sample pathping test:


Note: This pathping is for teaching purposes only, and does not indicate any past or current ISP issues.

Analyzing my 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.
