.tw is theInternetcountry codetop-level domain (ccTLD) for theRepublic of China, commonly known as Taiwan. The domain name is based on theISO 3166-1 alpha-2 country codeTW. The registry is maintained by the Taiwan Network Information Center (TWNIC), a Taiwanese non-profit organization appointed by theNational Communications Commission (NCC) and theMinistry of Transportation and Communication. Since 1 March 2001, TWNIC has stopped allowing itself to sign up new domain names directly, instead allowing new registration through its contracted reseller registrars. As of May 2023[update], there are 17 registrars.[1]

Internationalized domains

[edit]

Domain names inChinese characters may also be registered at the second level. Furthermore, any registrant of a standard domain name who has chosen a domestic registrar may automatically get two more domain names in Chinese characters in the followingsecond-level domains:網路.tw,組織.tw and商業.tw. These second-level domains correspond tonet.tw,org.tw andcom.tw, respectively.

ICANN assigned twointernationalized country code top-level domains (IDN ccTLDs) for Taiwan on 25 June 2010:[3]

Since at least November 2015,[4] the simplified suffix is a DNAME alias for the traditional suffix. As a result, any subdomain of the traditional .xn--kpry57d TLD automatically has a CNAME alias from the simplified .xn--kprw13d TLD. The traditional suffix is in active use.
