How IDNs Work

Register and Resolve IDNs in Supported Scripts

Computer users around the world have adapted to using computer keyboards to input script in their language. They use different keyboards, soft keyboards or have operating systems that facilitate the input of the scripts. IDNs use the Unicode universal character set to register and resolve script differences to simplify native language navigation.

Registering an IDN >>

A registrant contacts an ICANN accredited registrar. The registrar will convert the local language characters into a sequence of supported characters using an ASCII compatible encoding (ACE). Then the registrar submits the ACE string to the VeriSign Shared Registration System (SRS) where it is verified and encoded.

IDN Resolution Process >>

When a user types an IDN in local language characters, an IDN resolution process is required to locate the corresponding Web site or email address. In order for resolution to occur, the IDN's local language characters must be transformed into an ACE string that the DNS understands. VeriSign has developed VeriSign® i-Nav plug-in that enables the resolution of IDNs for Microsoft Internet Explorer 5 or 6 users. Users can also download IDNA enabled browsers such as Microsoft Internet Explorer 7 and Firefox. View a list of sample applications that support IDNs.

User Experience >>

Users enters an IDN in local language characters and it is resolved to navigate to the Web site.
