Domains by Country / Domain Names by Country 2024
Domain names for countries are determined by the Internet Assigned Numbers Authority, which began officially providing a domain name by country in 2018, although the United States began using .us in 1985. They are a relatively new registration for domain names for the Internet.
Every domain name by country is two letters long and is developed by using the letters in the nation’s name. These two letters are called the country code to- level domain or also the ccTLD. Every country that uses these domain names must comply with international regulations.
The Most Common Domains by Country
Today, approximately 40 percent of the world’s millions of domain name registrations are ccTLDs. The first use began in 1985 with .us for the United States. Today there are over 300 ccTLDs, and over 156 million websites using ccTLDs by March 2021.
- ccTLD: Country code top-level domains (ccTLDs) indicate the site’s relation to a specific country or region (i.e. .uk for the United Kingdom) and are referred to as country code TLDs.
- DNSSEC: The Domain Name System Security Extensions (DNSSEC) is a feature of the Domain Name System (DNS) that authenticates responses to domain name lookups. It does not provide privacy protections for those lookups, but prevents attackers from manipulating or poisoning the responses to DNS requests.
- IDN: Internationalized Domain Names (IDNs) are domain names represented by characters other than the traditional ASCII characters (a through z). Such domain names could contain letters or characters from non-Latin scripts (for example, Arabic or Chinese).
