Antigua and Barbuda domain names use the ".ag" country code top-level domain (ccTLD), which is the official internet domain for the Caribbean nation. The .ag extension is also popular in German-speaking markets due to "AG" being the German abbreviation for Aktiengesellschaft, a public limited company. There are various second-level domains, such as .com.ag for commercial use and .org.ag for non-profit organizations, though registration is generally open to everyone worldwide without restrictions.
