IP Address Informer - A Desktop Support Tool

Last Updated May 28, 2023 by Tim Trott. First Published in 2013.

IP Address Informer is an easy way to give your users a way to help IT support staff by providing them the easiest IP Address lookup tool.

IP Address Informer is a simple system tray application that performs an IP address lookup for all LAN connections. IP Address Informer will show the current IP address of the user's machine so that they can let IT support staff know the IP Address to connect to remotely through Remote Desktop or VNC. No more talking users through using ipconfig or navigating network properties to lookup IP addresses!

You can also use this tool to check the IP address assigned to your computer and to find your IP address.

Using IP Address Informer is as easy as asking your users to place their mouse cursor over the thunderbolt icon on the bottom right-hand side of the screen next to the clock! It will then pop up a tooltip stating their local IP address on the internal LAN.

You can download IP Informer below, and the C# source code is listed below if you want to compile your own version. The complete source code and project files are included in the download.
