Fields

All All All All 2

This value will convert any Unicode domain names to their Punycode equivalents (IDN names).

AllExceptIntranet AllExceptIntranet AllExceptIntranet AllExceptIntranet 1

This value will convert all external Unicode domain names to use the Punycode equivalents (IDN names). In this case to handle international names on the local Intranet, the DNS servers that are used for the Intranet should support Unicode names.

None None None None 0

This value will not convert any Unicode domain names to use Punycode. This is the default value which is consistent with the .NET Framework 2.0 behavior.

Remarks

The existing Uri class has been extended to provide support for International Resource Identifiers (IR) based on RFC 3987. Current users will not see any change from the .NET Framework 2.0 behavior unless they specifically enable IRI. This ensures application compatibility with prior versions of the .NET Framework.

The Internationalized Domain Name (IDN) attribute only controls IDN processing. All other IRI processing (character normalization, for example) is always performed by default.

The configuration setting for the System.Configuration.IdnElement will be read once when the first Uri class is constructed. Changes to configuration settings after that time are ignored.

For more information on IRI support, see the Remarks section for the Uri class.
