Software & aids for IDN

Web browsers with IDN

To be able to handle IDN domain names (e.g. åäöéü), the applications must be adapted. This work is in progress, but many of the latest versions of common web browsers already support IDN, such as:

• Microsoft Internet Explorer 7.0 and later versions
• Netscape 7.1 and later versions
• Mozilla 1.4 and later versions
• Mozilla Firefox 0.6 and later versions
• Opera 7.11 and later versions
• Safari 1.2 and later versions

Plug-ins

VeriSign has developed a plug-in for the handling of IDN domain names in older versions of Microsoft Internet Explorer. Here, you can find more information on VeriSign’s plugin for IDN.

ISC also has a plug-in for older versions of Microsoft Internet Explorer:

Programming library

If someone has in-house developed applications for which he/she would like IDN support, one of the complete programming libraries available could be used:

• PHP (GPL-license, PHP-IDN)
• Perl (Net::LibIDN)
• Java or C-API (proprietary license, VeriSign)
• C-API (BSD-licens, ipnic)
• C-API (BSD-license, ipnic, idnkit)
