What is the difference between a top-level domain, a domain name and a subdomain?
On the Internet, a top-level domain (TLD) identifies the most general part of the domain name in an Internet address. A TLD is either a generic top-level domain (gTLD), such as “com” for “commercial,” “edu” for “educational,” and “org” for non-profit organizations, etc., or a country code top-level domain (ccTLD), such as “fr” for France, “ca” for Canada. “us” for the United States or “is” for Iceland.
