  RFC 3490 (rfc3490) - Internationalizing Domain Names in Applications (IDNA)
IDNA uses the Unicode character repertoire, which avoids the significant delays that would be inherent in waiting for a different and specific character set be defined for IDN purposes by some other standards developing organization.
The IDNA notion of equivalence is an extension of that older notion.
IDNA specifies that all internationalized domain names served by DNS servers that cannot be represented directly in ASCII must use the ACE form produced by the ToASCII operation.

The IDNA notion of equivalence is an extension of the old notion.
IDNA for Host Domain Names (IDNA-Host) ASCII Domain names used within URLs and email addresses are subject to restrictions specified in [STD3] for host names.
IDNA- Host is IDNA with [STD3] host naming restrictions applied to ASCII and Unicode domain names.

IDNA requires that implementations process input strings with Nameprep [NAMEPREP], which is a profile of Stringprep [STRINGPREP], and then with Punycode [PUNYCODE].
Non-domain-name data types stored in domain names Although IDNA enables the representation of non-ASCII characters in domain names, that does not imply that IDNA enables the representation of non-ASCII characters in other data types that are stored in domain names.
Implications for typical applications using DNS In IDNA, applications perform the processing needed to input internationalized domain names from users, display internationalized domain names to users, and process the inputs and outputs from DNS and other protocols that carry domain names.

 ICANN | ICANN Rio de Janeiro Meeting Topic: Internationalized Domain Names | 13 March 2003
IDNA will be a major step forward for the domain name system, but only if the DNS registries undertake to implement it in a thoughtful, responsible, and standards-compliant manner.
The deployment of IDNA within existing top-level domain registries is fundamentally a registry responsibility, and the registries will be in the best position to make appropriate implementation decisions themselves, and should have the freedom to make adjustments as experience dictates.
The broad availability of IDNA applications is vital to the deployment of IDNs and, to encourage applications to be written, it is vital to provide those applications an IDN registration system that operates strictly according to the published technical standards.

 EHS Company - - Primer: Internationalized Domain Names -
IDNA describes algorithms for the presentation and encapsulation of IDNs.
Full IDNA support requires that this conversion also be performed in reverse, presenting encoded domain names in their rich form.
Note that since IDNA does not preserve non-normalized information during conversion and encoding, it is not possible for the original name with mixed case and separated accents to be preserved.

 4.8.4 encodings.idna -- Internationalized Domain Names in Applications
The ACE form of the domain name is then used in all places where arbitrary characters are not allowed by the protocol, such as DNS queries, HTTP Host: fields, and so on.
This conversion is carried out in the application; if possible invisible to the user: The application should transparently convert Unicode domain labels to IDNA on the wire, and convert back ACE labels to Unicode before presenting them to the user.
When receiving host names from the wire (such as in reverse name lookup), no automatic conversion to Unicode is performed: Applications wishing to present such host names to the user should decode them to Unicode.

 [No title]
In particular, IDNA does not require any changes to DNS servers, resolvers, or protocol elements, because the ASCII name service provided by the existing DNS is entirely sufficient.
Adding IDNA support to an existing application entails changes to the application only, and leaves room for flexibility in the user interface.
IDNA still requires the updating of applications, but only for input and display of names, not for changes to the protocols.

 GNU Libidn: IDNA Functions
The IDNA document defines internationalized domain names (IDNs) and a mechanism called IDNA for handling them in a standard fashion.
IDNs use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today.
IDNA is only meant for processing domain names, not free text.

Yes, iDNA Match offers separate Family Kits for the purpose of storing other DNA samples for siblings and fathers (or in adoption cases).
This is because iDNA Match is only a collection and storage method of harmless buccal cells, (transfer of liability) not a procedure.
By offering iDNA Match tests to fathers and other siblings, the hospital can offset the initial investment costs.

Until IDNA becomes more well known, Message queries you whether IDNA encoding of the domain name really should occur.
If the variable is `nil' no IDNA encoding will ever happen, if it is set to the symbol `ask' the user will be queried (the default), and if set to `t' IDNA encoding happens automatically.
If you want to experiment with the IDNA encoding, you can invoke `M-x message-idna-to-ascii-rhs RET' in the message buffer to have the non-ASCII domain names encoded while you edit the message.

 Internationalized domain name - Wikipedia, the free encyclopedia
IDNA was designed for maximum backward compatibility with the existing DNS system, which was designed for use with names using only a subset of the ASCII character set.
ICANN issued guidelines for the use of IDNA in June 2003, and it was already possible to register.jp domains using this system in July 2003.
These attacks are not due to technical deficiencies in either the Unicode or IDNA specifications, but due to the fact that different characters in different languages can look the same, depending on the font used.

A note on terminology: In this memo, we use "network order" to describe the sequence of characters as transmitted on the wire or stored in a file; the terms "first", "next" and "previous" are used to refer to the relationship of characters in network order.
For the purposes of IDNA, a simpler algorithm may be defind that yields the same result within the constraints of this context, but may be easier for people to implement consistently.
Careful consideration of all the languages Alvestrand and Karp Expires April 16, 2007 [Page 6] Internet-Draft IDNA RTL fix Oct 2006 written in a given script, in consultation with all of the corresponding speech communities, is therefore needed before we can say with any degree of certainty that using that script for IDNs is unproblematic.

 Nominet consults on international domain names - ZDNet UK   (Site not responding. Last check: 2007-09-16)
IDNA uses combinations of the 37 core symbols to create the new symbols.
In theory, all Nominet needs to do to allow IDNA is change this rule, but in practice there are serious issues that need to be considered, said the organisation.
The second option is for Nominet to allow IDNA registrations but provide no new infrastructure, which would be very little trouble for Nominet but would mean the domain name lookup service WHOIS would not return a result for café.co.uk even if xn--caf-fsa.co.uk was registered.

 ICANN | IDNA Protocol Review and Proposals for Changes
In follow up to the RFC4690 that was made available in September and announced on http://www.icann.org on 19 October 2006, a review of the IDNA protocol is underway.
The review is managed through the IAB and the IETF and was initiated to revise the protocol from being based on the Unicode version 3.2 (as was the latest version at the time of the development of the protocol in 2003) to the current version 5.0 of Unicode.
This paper is discussing issues related to language specific character issues where the same script is used across different language, issues related to cases where languages can be expressed by using more than one script, bi-directional cases as well as the topic of visually confusing characters.

If it fails, then the input domain name cannot be used as an Internationalized Domain Name and the application should have methods defined to deal with the failure.
Note: IDNA RFC specifies that a conformant application should divide a domain name into separate labels, decide whether to apply allowUnassigned and useSTD3ASCIIRules on each, and then convert.
