Question:

Answer:

Your computer's IP address may be outside of the accepted range of addresses managed by CNS (Communications Network Services). For a list of accepted ranges, look for "CNS" under the "Managed By" section of the Addresses table on the Virginia Tech IP Addresses Web page (http://www.computing.vt.edu/internet_and_web/internet_access/ipaddresses.html).

To verify that your computer is using a Virginia Tech IP address, try one of the following methods:

• Locate your IP address. To do this, go to the Webbed Who_OU page (http://www.w2k.vt.edu/who_ou.php).
• Try to ping one of the restricted access domain controllers.
  1. Click the Start button, and select Run.
  2. In the Open text box, type: cmd
  3. Click OK.
  4. At the prompt, type: ping gc.w2k.vt.edu
  5. Press the Enter key. If you cannot ping the domain controller, your computer is outside of the acceptable range.

If your IP address does not fall into an acceptable range, set up a VPN client to tunnel network traffic through to an inside address. For more information, refer to the Virtual Private Network (VPN) Access page (http://www.computing.vt.edu/internet_and_web/internet_access/vpn.html).
