.tw

.tw is the Internet country code top-level domain (ccTLD) for the Republic of China, commonly known as Taiwan. The domain name is based on the ISO 3166-1 alpha-2 country code TW. The registry is maintained by the Taiwan Network Information Center (TWNIC), a Taiwanese non-profit organization appointed by the National Communications Commission (NCC) and the Ministry 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]

Certification Authority being the most popular SSL certificate.^[2] Apache is the most popular web server, serving 47.60% of the .tw domains, followed by Microsoft-IIS serving 20.31% of the total .tw domains.^[2]

Internationalized domains

Domain names in Chinese 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 following second-level domains: 網路.tw, 組織.tw and 商業.tw. These second-level domains correspond to net.tw, org.tw and com.tw, respectively.

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

• .台灣 : Taiwan in traditional Chinese characters (DNS name: .xn--kpry57d)
• .台湾 : Taiwan in simplified Chinese characters (DNS name: .xn--kprw13d)

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.
