IP Address Troubleshooting - Verifying a correct IP address

Being unable to connect to the internet and getting a local only access on a computer can frequently be due to invalid IP addresses or the computer being unable to attain a Default Gateway. This guide will walk through checking the IP address the computer is getting and troubleshooting the different issues caused by different IP addresses.
  1. Click the Start button in the lower left-hand corner of the screen and type CMD in the Search Programs and Files field and press Enter.


  2. In the command prompt window that appears, type IPCONFIG and press Enter.


  3. The two most important pieces of information displayed will be the IPv4 address and Default Gateway.

    command prompt window

    • If the IPv4 Address is, contact your Internet Service Provider or check out our Router Troubleshooting article here.
    • If the IPv4 Address begins with 169.254.xxx.xxx, check out our 169.254 IP Address troubleshooting article.
    • If the IPv4 Address begins with 192.168.xxx.xxx, verify the default gateway.
