This application is a GUI front-end for DIG program - "lookup utility". Application is designed only for public name servers. In addition you can send emails with query results and access major free resolvers.
dig (domain information groper) is a flexible tool for interrogating DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than dig.
