Opening INS files

Did your computer fail to open an INS file? We explain what INS files are and recommend software that we know can open or convert your INS files.

What is an INS file?

INS is an acronym for Internet Naming Service. Files that contain the .ins file extension are commonly used to reconcile alphanumeric Web addresses into strictly numeric IP Web addresses. For example, if a website had a URL named, that URL would be converted into a purely numeric IP address using the INS file format. This IP address would then be recognized by the necessary Web services.

The .ins file extension is also used for a computer user's Internet settings files. These files determine how the user's computer will access a dial-up or broadband Internet connection. These INS files are normally stored in a text-based format.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
