An Internationalized Domain Name (IDN) is an Internet domain name that contains at least one label that is displayed in software applications, in whole or in part, in a language-specific script or alphabet, such as Chinese, Russian or the Latin alphabet-based characters with diacritics, such as French. These writing systems are encoded by computers in multi-byte Unicode. Internationalized domain names are stored in the Domain Name System as ASCII strings using Punycode transcription.
The Domain Name System, which performs a lookup service to translate user-friendly names into network addresses for locating Internet resources, is restricted to the use of ASCII characters, a technical limitation that initially set the standard for acceptable domain names. The internationalization of domain names is a technical solution to translate names written in language-native scripts into an ASCII text representation that is compatible with the Domain Name System. Internationalized domain names can only be used with applications that are specifically designed for such use, and they require no changes in the infrastructure of the Internet.
IDN was originally proposed in December 1996 by Martin Dürst and implemented in 1998 by Tan Juay Kwang and Leong Kok Yong under the guidance of T.W. Tan. After much debate and many competing proposals, a system called Internationalizing Domain Names in Applications (IDNA) was adopted as a standard, and has been implemented in several top-level domains.
In IDNA, the term internationalized domain name means specifically any domain name consisting only of labels to which the IDNA ToASCII algorithm (see below) can be successfully applied. In March 2008, the IETF formed a new IDN working group to update the current IDNA protocol.
In October 2009, the Internet Corporation for Assigned Names and Numbers (ICANN) approved the creation of country code top-level domains (ccTLDs) in the Internet that use the IDNA standard for native language scripts, i.e. internationalized country code TLDs. In May 2010 the first IDN addresses became live.

To improve performance of WHOIS service and to prevent its excessive high-volume use by a single source, we implemented a randomly generated Access Code that must be entered before running a WHOIS request.
The Access Code in the box is provided in graphics format. It has letters which are generated randomly and the symbol images are distorted. The distorted symbols cannot be read by computer programs which are used for mass-collect email addresses and any customer information. Only humans can read the distorted symbols and pass the access code.
The Access Code improves performance of our services. It prevents excessive high-volume use by a single source.
The services that require Access Codes are:
Whois – after entering the correct Access Code you can run 10 WHOIS requests before you will be prompted to enter a new Access Code.
Site Info – you can run 25 Site Info requests before you will be prompted to enter an Access Code.
Trace Route - you can run 20 Trace Route requests before you will be prompted to enter an Access Code.
RBL Check - you can run 20 RBL Check requests before you will be prompted to enter an Access Code.
What’s my IP - Access Code is not required for this service.
NOTE: We may modify Access Code policy at any time without notice on this web page.
