Mozilla 1.4, Netscape 7.1, Opera 7.11 and Safari are among the first applications to support IDNA. Internet Explorer 7.0 and Windows Vista's URL APIs provide native support for IDN. Therefore these web browsers don't need any modifications to visualize IDN domains properly. A browser plugin is available for Internet Explorer 6 to provide IDN support.

The i-Nav and Components suite encompasses multiple modules which bring IDN support to various Windows applications that do not support IDNs natively. Currently, i-Nav supports all versions of Internet Explorer up to version 6.0, Microsoft Outlook 2000, XP and 2003,Outlook Express 6.0, and the Windows Address Book for Windows 98, 2000, and XP.
