IDN stands for Internationalized Domain Name. It refers to a domain that includes characters from native languages, allowing the use of non-Latin scripts such as German, Spanish, Russian, Chinese, Arabic, and many others.
The main advantage of IDN domain names is that they enable you to reach your audience in their native language. Since most modern web browsers and email platforms now support non-English characters, many online businesses are recognizing the value of IDNs, leading to their increasing adoption. Additionally, IDN domains can enhance Search Engine Optimization (SEO) by allowing you to target the exact keywords that non-English users enter when searching online.

Domain Name Servers (DNS) are limited to using the English alphabet (A–Z), numbers (0–9), and a few punctuation marks such as hyphens and dots. To work around this restriction, a system called Punycode was introduced to make it possible to use non-English characters in domain names.Punycode works by converting characters from other languages into a format that DNS can understand. For example, the domain españa.com is transformed into xn--espaa-rta.com when encoded with Punycode. This converted version is known as an ACE (ASCII Compatible Encoding) string. When you register an Internationalized Domain Name (IDN), what is actually stored in the DNS is the ACE string, since it contains only supported characters.
