A device's IP address can give helpful and specific information about its network situation, such as whether or not it's successfully registered and what building it's in (or supposed to be in). Detailed information about IP ranges at Gustavus can be found on the GReg IP address ranges page.
Determining an IP address
A device's IP address can be a great aid in troubleshooting networking problems.
To find your IP address using Windows, you can follow these steps:
- Type cmd in the search to open the Windows command prompt.
- At the prompt, type ipconfig, and one of the items listed should be your IP Address (IPv4).
Alternatively, if you have chosen to display your network status in the system tray, you can double click the network connection's icon (two computers blinking light and dark blue) and click on the Support tab, and the IP address should be listed.
Mac OS X
To find your IP address in Mac OS X, you can follow these steps:
- Choose System Preferences. from the Apple menu.
- Click on the Network icon.
- Choose the network connection (probably Built-in Ethernet).
- Your IP Address should be displayed.
On most Unix-like OS's such as Mac OS X and various distributions of Linux and BSD, you can run the ifconfig command in a terminal shell to determine your IP address. Note that you may need to be an administrator on the computer (i.e. logged in as root or using sudo) to perform this command.
