Country Code
312 件のトップレベルドメイン
Country code top-level domains (ccTLDs) are two-letter domain extensions assigned to countries and territories based on ISO 3166-1 alpha-2 codes. Managed by designated national registries, ccTLDs like .uk (United Kingdom), .de (Germany), .jp (Japan), and .br (Brazil) serve as digital identifiers for nations on the internet. Some ccTLDs restrict registration to local residents or businesses, while others — such as .io (British Indian Ocean Territory), .ai (Anguilla), and .tv (Tuvalu) — have become popular globally due to their appeal in the tech and media industries. IANA delegates ccTLD management to local operators, and each registry sets its own pricing, registration policies, and dispute resolution procedures. ccTLDs are often preferred for local SEO, as search engines may associate them with geographic relevance.
