C-IP is a useful tool for viewing your WLAN/Public IP without the need of using the command-line.

There is no real set up to speak of, just run it, and the details are displayed in the systray for fast and efficient at-a-glance viewing by right-clicking the app's icon. No additional settings are available other than the ability to copy either WLAN or the public IP to the clipboard.

C-IP can be useful for quick sharing of the displayed data and will be of particular interest to users that are unfamiliar with command-prompt. It is easy-to-use and doesn't take up many resources when in use.
