IP Lookup provides you with a simple option for looking up your internal and external IP addresses.
IP Lookup is a simple and to the point utility that has a specific job and does it well. IP Lookup is displayed from a minimalistic interface that does offer a few settings like always on top and language selection. It can be portable if desired. To activate the portable mode, create "iplookup.ini" in the application folder, or move it from "%APPDATA%Henry++Ip Lookup."
