The document discusses Internationalized Domain Names (IDNs) and how they allow domain names to be registered in local languages and scripts beyond just the Latin alphabet. It explains that traditionally only Latin letters a-z were allowed in top-level domains (TLDs) but starting in 2009, IDNs introduced non-Latin characters from other scripts. Now over 70 IDN TLDs have been created in languages like Arabic, Chinese, and Cyrillic through programs that establish country-specific and generic TLDs in local scripts. The goal is for the Domain Name System to be fully internationalized to connect more internet users around the world in their own languages.
