Country domains (ccTLDs)
Every country code top-level domain, the two-letter internet suffix such as .se (Sweden) or .io (British Indian Ocean Territory). Each links to the country behind it.
A ccTLD is derived from a country’s ISO 3166-1 code. Some, like .io, .co and .tv, are also widely used far beyond their home country.
ccTLD assignments from open datasets (IANA / ISO 3166-1). Full sources on the data page.
