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). 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 Zone in April, 2010; it is estimated that 60% of users now access the Internet in their native, non-English language. IDN can also be perceived as the label displayed in a software application, in an alphabet or language-specific script. IDNs are stored in the DNS as ASCII strings.

Name Collision
A Name Collision describes the circumstance in which a term attempting to reach a private Domain Name results in resolving to a public Domain Name unintentionally. Private domain names are used in Intranets and in many corporations and organizations throughout the world. A domain name on a private network that matches a name in the public Internet can create security risks, confusion, and systems failure. Although the Name Collision issue is not new, a renewed interest in the issue came about in 2013 as ICANN's New gTLD Program was preparing to delegate hundreds of new domain names to the Root Zone. The topic was debated fiercely within the ICANN community when a report by Interisle Consulting was prepared for and released by ICANN.
