IP Address Informer is an easy way to give your users a way to help IT support staff by providing them with 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 users 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 address!

You can also use this tool to check 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 popup a tooltip stating their local IP address on the internal LAN.

    This tool would make life a lot easier for dealing with our computer illiterate users.

    Do you know how I can deploy this to every desktop automatically? Then it would be perfect!

    Thanks for your effort!

      Hello IT Guy

      I've created an MSI installer for IPInformer, and you should be able to deploy it using a group policy using the tutorial here

      Hope that helps
