Country code top-level domain : ウィキペディア英語版 | Country code top-level domain
A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, a sovereign state, or a dependent territory. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs. In 2010, the Internet Assigned Numbers Authority (IANA) began implementing internationalized country code TLDs, consisting of language-native characters when displayed in an end-user application. Creation and delegation of ccTLDs is described in RFC 1591, corresponding to ISO 3166-1 alpha-2 country codes. ==Types== (詳細はinfrastructure top-level domain (ARPA) *generic top-level domains (gTLD) *restricted generic top-level domains (grTLD) *sponsored top-level domains (sTLD) *country code top-level domains (ccTLD) *test top-level domains (tTLD)
