What are the most commonly used domain name suffixes on the Internet? When are they used?

As a website operator, I feel that in recent years, various domain name extensions have suddenly emerged in the domain name industry. In my memory, there are only 9 commonly used domain name suffixes, and there are various new ones. So what are the most common domain name suffixes on the Internet? When are they used? Let's learn more about it below!

Domain name is what we often call a website address, which is used to replace the hard-to-remember IP address and identify the electronic location of the computer during data transmission. It is divided into top-level domain name, second-level domain name, subdomain name, etc.

Commonly used domain name suffixes

1.com (commercial/company)

.com domain name originally means "commercial" or "company", which means business, company, and enterprise. .com is currently the most widely used universal domain name format in the world, with more than 110 million users worldwide.

Currently, almost all commercial websites use .com domain name, such as vname.com, baidu.com, bieshu.com, etc. It is the most common domain name suffix on the Internet.

2.net (network)

.net domain name was born in the 1980s. .net domain names are generally used by organizations or companies that provide Internet-related network services.

3.org (Organization)

.org domain name is the third largest international top-level domain name in the world. Its history can be traced back to 1985, when the .org domain name and six other domain names (.com, .us, .edu, .gov, .mil and .net) were first introduced, meaning Organizations.

Unlike .com, which has the largest number of registrations, the commercial and corporate attributes are no longer so obvious. The organizational meaning of the .org domain name is still very strong, and the impression on visitors is that when they see the .org domain name, they will think that it should be the domain name of the organization.

4.gov (Government)

.gov domain name is the abbreviation of Government, and the .gov domain name is a domain dedicated to the US government.

.gov.XX: Since the .gov domain name is a domain dedicated to the US government, governments of other countries cannot register and use the .gov domain name, so other countries use .gov + their own country/region area as the authoritative government domain name. .XX is the country domain name suffix of each country, such as .http://gov.cn.

5.edu (education)

.edu: The .edu (education) domain name is mainly used by educational institutions, such as universities and other institutions. It was originally used by educational institutions around the world. Before that, many .edu domain names had nothing to do with universities. However, after October 29, 2001, the U.S. Department of Commerce signed a cooperation agreement with EDUCAUSE. From that day on, only accredited higher education institutions in the United States could submit new domain name applications. However, if the original non-U.S. institutions had registered the .edu domain name before that date, they could still retain their registration status indefinitely. Therefore, this top-level domain is a domain dedicated to American universities and educational institutions.

.edu.XX: Since the .edu domain name is a domain name exclusively used by accredited higher education institutions in the United States, educational institutions and universities in other countries cannot register and use the .edu domain name. Therefore, other countries generally use .edu + their own country/region domain name as the exclusive domain name for educational institutions, where .XX is the country domain name suffix of each country, such as .http://edu.cn: http:/singhua.edu.cn (Tsinghua University), http://pku.edu.cn (Peking University).

6.mil (military)

.mil: The .mil (military) domain name is a domain name exclusively used by the US military website.

.mil.XX: Also, since the .mil domain name is a domain name exclusively used by the US military, other countries use .mil. their own country domain names to reflect the "military" attribute. Where .XX is the country domain name suffix of each country, such as .http://mil.cn.

7.int (international organization)

.int: The .int (International) domain name is a domain name exclusively used by international organizations. This domain name is assigned to international standardization groups, intergovernmental organizations, treaty bodies, the United Nations and its subordinate agencies, and is used by the International Union, the European Union (EU), the North Atlantic Treaty Organization, the International Telecommunication Union, the International Civil Aviation Organization, the Interpol police agency, etc. However, most international organizations generally use the org domain name, one of the gTLDs that ordinary non-profit organizations can register, or the ccTLD (country-specific top-level domain name) where the headquarters is located, and do not use the .int domain name very much.

8.cn (China country domain name)

.CN domain names belong to national and regional top-level domain names. CN is the ISO Code, representing China. China Internet Network Information Center (CNNIC) is the .CN domain name registration and management agency, responsible for operating and managing the corresponding .CN domain name system and maintaining the central database.

9.com.XX, .net.XX, .org.XX

XX is a country/region domain name, such as .com.cn, .net.cn, .org.cn. Some countries also use short domain names, such as the United Kingdom (.co.uk), Japan (.co.jp, .ne.jp, .go.jp), India (.co.in)

Such domain names reflect the meaning of top-level domains in the country/region, such as .com.cn reflects the commercial and company websites in China. In many countries such as the United Kingdom and Japan, such domain names can only be registered and used by enterprises.

The above are the 9 commonly used suffixes on the Internet. Which domain name suffix do you usually see?
