Internationalized Domain Name

An Internationalized Domain Name (IDN) is an Internet domain name that uses the latest ICANN protocols and standards to support domain names written in multiple scripts and languages (non-ASCII characters). As of February 2022, 92 IDN gTLDs and 61 IDN ccTLDs have been delegated. They allow users to navigate the Internet without using English, which was long considered the default Internet language despite the Internet's growing base of international users. The first IDNs were implemented into the root in April 2010; it is estimated that 60% of users now access the Internet in their native, non-English language.[1] Since the development of initial guidelines, ICANN has adhered to the protocols and standards proposed by RFCs 3490, 3491, and 3492.[2] [3]

Name Protocols edit

IDNs are specialized labels displayed in a software application in a non-Latin alphabet or language-specific script. IDNs are stored in the DNS as ASCII strings. The DNS performs look-up services to ensure the translation of user-friendly names to locate the Internet resources, and it is restricted to using ASCII characters for acceptable domains. The "nameprep" protocol ensures the names written by means of non-ASCII scripts are translated into ASCII text compatible with the DNS.[4]

The syntax designed for the use of the IDN is known as "Punycode."[5] The non-ASCII characters are transformed into a specific format containing only ASCII characters and then a unique identification is processed for the domain name. [6]

In order to see and use the characters found in IDNs, various changes and specific settings may need to be manipulated within the web browser, or the installation of foreign language packs may be required.

History edit

The IDN was proposed by Martin Dürst in 1996 and implemented in 1998 by Tan Juay Kwang and Leong Kok Yong. Later on, the IDNA system (Internationalizing Domain Names in Applications) was adopted and implemented in some top-level domain names. According to the IDNA system, an "internationalized domain name" signifies any domain name which contains labels on which the IDNA ASCII algorithm could be applied. James Seng (ChingHong Seng) has been credited as a primary inventor of IDNs.[7] In the early stages of his career, James Seng's mentor Dr. Tan Tin Wee inspired him to work on IDNs to curb the digital divide in Asia. With $24 million in investment from Venture Capital firms General Atlantic Partners and Network Solutions/Verisign, James went on to become the founder and CTO of i-DNS.net. During this time, he was working on the standardization of IDNs as the Co-Chair of the IDN Working Group at the IETF. He also stressed the need for IDNs at various forums such as ICANN, ITU and IGF and his efforts have helped make IDN an Internet standard. In India XgenPlus Email software has successfully started offering email services in all Indian languages on IDN domain names.

An important milestone in the development of IDN TLDs was the October 2009 ICANN meeting in Korea. At the meeting, the ICANN Board approved the IDN ccTLD Fast Track Process that enabled countries to offer national domain names with non-Latin characters. At that time, ICANN accepted the development of IDN ccTLDs on the Internet using IDNA standards. [8]

ICANN Approves Delegation of IDN ccTLDs edit

The first IDN ccTLDs were successfully implemented into the DNS root zone in May, 2010, these included Russia (.рф), Egypt (صر.), Saudi Arabia السعودية.) and United Arab Emirates (امارات.).[9] In August 2010, ICANN approved the delegation of the Arabic script TLDs for Palestine (فلسطين.), Tunisia (تونس.) Jordan (الاردن.), Thailand (.ไทย) and the two IDN ccTLDs for Sri Lanka (.ලංකා) and (.இலங்கை.[10] ICANN also approved the Arabic script ccTLD for Iran, India, Qatar, Singapore, Syria, and Taiwan.[11]

Rejected IDN ccTLDs edit

The internet governing body has twice rejected the IDN application of the Bulgarian government for .6r, the Cyrillic translation of .bg due to its close similarity with the .br, ccTLD for Brazil.[12] In an interview, Bulgaria's Technology Minister Alexander Tsvetkov said that his government will appeal to ICANN to reconsider its decision. [13] In addition, Bulgaria's Deputy Transport Minister stated the government might modify its application or wait for the launching of an appeals procedure. He hoped that ICANN will accept their proposal by the end of 2011. Meanwhile, the Brazilian government supported ICANN's decision to reject .6r, saying that "any graphic confusion might facilitate phishing practices" and other related problems.[14]

At ICANN 44 in Prague, the GAC addressed rejected IDN ccTLDs. Their communique asked ICANN to "urgently reconsider" its ruling, as they saw the move as having "erred on the too-conservative side, in effect applying a more stringent test of confusability between Latin and non-Latin scripts than when undertaking a side by side comparison of Latin strings." While not all of the rejected strings were addressed directly, the communique was understood to address ICANN's rejection of the aforementioned .6r from Bulgaria, Greek's .ελ (short for Ελλας, or Hellas), and a Greek transliteration of .eu). .ελ was rejected because of its similarity to .EA, which is a reserved 2 character ccTLD on the ISO-3166 list,[15] while the other was too similar to Estonia's .ee.[16]

IDN New gTLDs edit

See a list of all IDN New gTLD applications here.

It was revealed in June 2012 that 116 IDN New gTLD Program had been applied for, 73 of them being the Chinese language. Approximately half of these Chines TLDs come from mainland China, but a significant number of them were applied for by non-Chinese companies. Because of the restriction against single-character TLDs, many companies who would have applied for "网" (web) and "店" (shop), instead were forced to apply for "网站" (website) and "网店" (web-shop). The biggest IDN applicant was Zodiac, which applied for 15 Chinese TLDs. Verisign applied for 12 foreign language transliterations of .com and .net. The languages with the second highest number of applications were Arabic (15) and Japanese (9).[17]

Likely as part of the new ICANN CEO's Fadi Chehadé's internationalization of the organization, IDN gTLD applications were given priority in the batching process. Batching is a term used to describe the prioritization of applications in such a way that ICANN staff can deal with them in an organized and efficient manner. The final process used to batch was a lottery, where applications were pulled at random. IDN applications were given the option to go first in this system.[18]

Synchronized IDN edit

A Synchronized Internationalized Domain Name (IDN) refers to a set of domain names that are equivalent across different scripts or languages but are synchronized to resolve to the same website or web page.

By Country or Region edit

India edit

In 2013, the Government of India started a domain name registry for .bharat (in Hindi) IDNs in multiple regional languages. In support of that XgenPlus - an Indian email solutions company started to offer IDN compliant email server and hosted email services much before Gmail / Office365 and yahoo.

Iran edit

In 2013 the ccTLD registry, IRNIC, transitioned existing IDN registrations at the second level under .ir to full IDNs under .ایران.[19]

Italy edit

Beginning on July 11, 2012, all .it domain names began allowing Internationalized Domain Names (IDN), allowing them to support Italian, French, and German accents and characters. In five minutes, 1,737 new IDNs were registered; in thirty, 2,620; in four hours, eight thousand.[20] The first .it IDN name, registered in three seconds, was perché.it, followed by perchè.it, a misspelling of the former. Common words were registered in the first hours, along with accented words that are usually devoid of accents, such as "agentì", "pizzà", and "ìtalià". Non-Italian proper nouns were also registered in their native tongue, in the case of IDNs related to Austria -- österreich.it -- and the German city Cologne -- köln.it.[20]

Turkey edit

With 10,000 IDNs, Turkey has half the IDNs in the MEAC (Middle East and Adjoining Countries) region, at the second level, under .tr.[19]

Middle East Region edit

As of December 2014, 2̬% of the existing 91,000 full IDNs were in Arabic script, and the leading ones were .موقع (.mawqe, aka "site") and .شبكة (.shabaka, aka "web"). The strong performers in the region are the United Arab Emirates, Saudi Arabia, Egypt, and the Islamic Republic of Iran.[19]
