Title: Variants in Second-Level Names Registered in Top-Level Domains Author: J. Levine, P. Hoffman Status: Informational Stream: Independent Date: May 2013 Mailbox: standa...@taugh.com, paul.hoff...@vpnc.org Pages: 18 Characters: 39615 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-levine-tld-variant-06.txt URL: http://www.rfc-editor.org/rfc/rfc6927.txt Internationalized Domain Names for Applications (IDNA) provides a method to map a subset of names written in Unicode into the DNS. Because of Unicode decisions, appearance, language and writing system conventions, and historical reasons, it often has been asserted that there is more than one way to write what competent readers and writers think of as the same host name; these different ways of writing are often called "variants". (The authors note that there are many conflicting definitions for the term "variant" in the IDNA community.) This document surveys the approaches that top-level domains have taken to the registration and provisioning of domain names that have variants. This document is not a product of the IETF, does not propose any method to make variants work "correctly", and is not an introduction to internationalization or IDNA.
