Internationalized Domain Names in Applications : Protocol
RFC 5891, “Internationalized Domain Names in Applications : Protocol”, is a Proposed Standard document published in August 2010 by J. Klensin. It updates RFC 3492. It obsoletes RFC 3490, RFC 3491. The canonical text is published by the RFC Editor.
Abstract
This document is the revised protocol definition for Internationalized Domain Names (IDNs). The rationale for changes, the relationship to the older specification, and important terminology are provided in other documents. This document specifies the protocol mechanism, called Internationalized Domain Names in Applications (IDNA), for registering and looking up IDNs in a way that does not require changes to the DNS itself. IDNA is only meant for processing domain names, not free text. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
The canonical text of RFC 5891 is hosted at rfc-editor.org. Available in TXT,HTML.
