Auto IP Addresses

If DeviceInstaller reported an Auto IP address issue, your PC is configured to obtain an IP address automatically from a server on the network. If Windows does not obtain an IP address, it defaults to an Auto-Configuration IP Address.  DeviceInstaller is not be able to assign an IP address to your Lantronix device if your PC is using an Auto-Configuration IP address.

To check whether your PC is using an Auto-Configuration IP address in Windows 2000 or XP:

  1. Click Start and select Run.

  2. At the Open prompt, type cmd. A command window opens.

  3. At the command window, type ipconfig. Your Windows TCP/IP configuration displays.

To check your PC’s current IP configuration on Windows 98:

  1. Click Start and select Run.

  2. At the Open prompt, type command. A command window opens.

  3. At the command window, type ipconfig. Your Windows TCP/IP configuration displays.

To resolve the issue:

If your PC is using an Auto-Configuration IP address, it has an IP address like 169.254.XXX.XXX, where the X’s are randomly chosen numbers. Notice that the first two octets of the IP address are 169.254, indicating an Auto-Configuration IP address.

To resolve this issue, configure your PC with a static IP address. For more information on configuring a static IP address in Windows, see the Windows help files. You can access the Windows help files by clicking the Windows Start button and selecting Help. Search in Windows help for static IP addresses.
