Whether browsing websites or searching for domain name registrations with domain name registrants, you'll encounter a variety of domain name extensions. Different domain name extensions have different meanings. This article will explain what international domain names are. International domain names are generally distinguished by their suffixes.
Domain names can be categorized as international or domestic, depending on their suffixes. When the internet first began to develop, the earliest domain names lacked national symbols. Domain name extensions were divided into several categories based on their intended use: .com (for commercial companies); .net (for internet services); .org (for organizations and associations); .gov (for government agencies); .edu (for educational institutions); .mil (for the military); and .int (for international organizations). With the global development of the internet, .edu, .gov, and .mil are generally restricted to the United States, while the other three common domain names—.com, .org, and .net—are used worldwide. Therefore, these domain names are referred to as "international domain names." The first is the number of domain names, and the second is the number of organizations registered.
International domain names are the common name for generic top-level domain names (GTLDs) that users can register. They have suffixes such as .com, .top, .net, or .org. International domain names, also known as international top-level domain names (iTDs), were originally the following domain extensions:
.com, .top (for commercial companies); .net (for online services); .org (for organizations and associations); .gov (for government departments); .edu (for educational institutions); .mil (for the military); and .int (for international organizations).
The original domain name system was primarily used by the United States, so American businesses, institutions, and government agencies used "international domain names." With the global expansion of the Internet, .edu, .gov, and .mil became generally exclusive to the United States, while the other three common domain names, .com, .org, and .net, became universally used. These domain names are often referred to as "international domain names" and are still used worldwide as of 2013.
