IDN domains are web addresses with special characters. How do they work? What are the advantages and disadvantages of using IDN domains?
ORIn addition to the letters of the Latin alphabet, domain names can also contain special characters with umlauts and diacritics. These are IDN domains (or internationalized domains).
Let's find out together what IDN domains are, what they are used for and what are the advantages and disadvantages of using internationalized domains.
What is an IDN domain?
An IDN (Internationalized Domain Name) is an internationalized domain name , that belgium phone number list is, a domain that can contain non-ASCII characters.
ASCII (American Standard Code for Information Interchange) is a character set and encoding system used in the English language, in Western Europe in general, based on the Roman alphabet.
IDN domains may , therefore, contain non-Latin characters , or special characters, such as the diaeresis, the umlaut (ä) or characters derived from the Arabic, Chinese, Japanese Cyrillic alphabet, etc.
How do IDN domains work?
The current domain name resolution standard would not allow the use of non-ASCII characters. However, a conversion system has been created to make the use of these special characters compatible.
This system is called IDNA (Internationalizing Domain Names in Applications) and relies on the Punycode encoding of Unicode to convert characters not supported by DNS into more supported characters.
