.tw is the Internet country code top-level domain (ccTLD) for 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]
Second-level domains
[edit]Registrations under .tw are possible in second-level space or under various domains as third-level domains:
- edu.tw: for educational and academic institutions
- gov.tw: for agencies of the Government of the Republic of China
- mil.tw: for the Republic of China Armed Forces
- com.tw: for companies or firms
- net.tw: for network or telecommunications license holders
- org.tw: for non-profit organizations
- idv.tw: for individuals (must verify their identity by e-mail)
- game.tw: unrestricted (but registrant must verify their identity by email), intended for gaming-related content
- ebiz.tw: unrestricted (but registrant must verify their identity by email), intended for online business-related content
- club.tw: unrestricted (but registrant must verify their identity by email)
- tw: unrestricted
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.
Statistics
[edit]As of March 2017, around 8.31％ of the .tw domains are served via secured HTTPS protocol, with the cPanel, Inc. 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
[edit]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.
