Abstract

This document supplies the protocol definition for Internationalized Domain Names in Applications (IDNA), with the version specified here known as IDNA2008. Essential definitions and terminology for understanding this document and a road map of the collection of documents that make up IDNA2008 appear in a separate Definitions document [RFC5890]. Appendix A discusses the relationship between this specification and the earlier version of IDNA (referred to here as "IDNA2003"). The rationale for these changes, along with considerable explanatory material and advice to zone administrators who support IDNs, is provided in another document, known informally in this series as the "Rationale document" [RFC5894].

     Internationalized Domain Names in Applications (IDNA): Protocol

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.
