Glossary entry for `IDN`

IDN
The original specifications for the Domain Name System (DNS) limited the characters that were allowed in domain names to the set of alphanumeric characters in ASCII, plus the hyphen (-) and the period (.). As the Internet spread out across the world, away from its North American origins, demand for a new system that supported the many different languages and scripts across the world grew. The term "Internationalized Domain Names" (or IDN) refers to a domain name that uses recently adopted standards that modify the existing DNS protocols and standards to support multiple languages and scripts.
