Country Code Top-Level Domains (ccTLDs) are two-letter domain extensions assigned to specific countries or territories. For example, ".uk" represents the United Kingdom, while ".jp" is for Japan. These domains help identify websites associated with a particular nation, promoting local content and services. Each ccTLD is managed by a designated organization within the respective country, ensuring that the domain is used according to local regulations. Some ccTLDs, like ".io" for British Indian Ocean Territory, have gained popularity beyond their geographic boundaries, often used by tech companies and startups for branding purposes.
