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.
