To determine your computer's IPv4 address, do the following:

1. In the Windows Search Bar, type 'cmd' in the search field and then click Command Prompt.
   1a. Make sure you are using the Search Field from your Desktop and NOT a Google internet search engine
2. Type ipconfig and press Enter.
3. Locate the line labeled Ethernet adapter Local Area Connection. Or, if you want to release/renew the IPv4 address for another adapter (like a wireless adapter), look for that instead.
4. Locate the line labeled IPv4 Address below Ethernet adapter Local Area Connection:.

Determine your IPv4 address and refer to the information below.

• 10. (example: 10.1.1.2) — An IPv4 address that begins with 10. has full access to the campus network and the Internet.
• 138.87. (example: 138.87.246.1) — An IPv4 address that begins with 138.87. has full access to the campus network and the Internet.
• 172. (example: 172.254.1.2) — An IPv4 address that begins with 172. has restricted access to the campus network and cannot access the Internet.
• 192.168. (example: 192.168.1.2) — An IPv4 address that begins with 192.168. is typically assigned by a personal router. Depending on your home or private network, you may or may not have access to the Internet.
• 169.254. (example: 169.254.1.2) — If you have a 169.254. IPv4 address, it means your computer is unable to obtain a valid IPv4 address from the network. You may attempt to obtain a valid IPv4 address by releasing and renewing.
• 0.0.0.0 — If your IPv4 address is 0.0.0.0, it means your computer currently has no IP address. You may attempt to obtain a valid IPv4 address by renewing.
• Other (example: any other IPv4 address) — If you have another IPv4 address listed, it may be one you obtained from your Internet Service Provider (ISP). Or, it might be a static IPv4 address configured in your computer's network settings.

To release and renew your IPv4 address, do the following:

1. Type cmd into the Search Field and then click on or choose to Open the Command Prompt.
2. A command prompt window will appear.
3. In the command prompt window, type ipconfig /release and press Enter (make sure there is a space between ipconfig and the forward slash / ).
4. The IPv4 configuration information will refresh. You should see your IPv4 address change to "0.0.0.0".
5. Type ipconfig /renew and press Enter (make sure there is a space between ipconfig and the forward slash / )
6. Your computer will attempt to obtain a new IPv4 address from the network. This may take a few minutes.
7. If this process is successful, you will see a new IPv4 address listed when the IPv4 configuration information refreshes.
