What are the categories of domain names? What do common domain name suffixes mean?

From a regional perspective, there are two types of domain names in China. One is Chinese domain names, which are used by fewer people, mainly because some browsers do not support Chinese domain name operations; the other is English domain names, which are used by many people. If divided by the Internet domain name system, it is divided into three categories, namely category top-level domain names, geographic top-level domain names, and new top-level domain names. Next, the editor of Juming.com will give you a detailed introduction to the domain name system division.

What categories are domain names divided into?

1. There are 7 category domain names (commonly called international domain names in spoken language), which are now commonly referred to as international domain names. Since the Internet originated in the United States, the earliest domain names did not have national identification. People divided them into several major categories according to their uses, and they ended with different suffixes: .com (for commercial companies); .net (for network services); .org (for organizations and associations, etc.); .gov (for government departments); .edu (for educational institutions); .mil (for the military field); .int (for international organizations).

2. It is a country domain name (geographic top-level domain name), with a total of 243 country and region codes, such as .CN for China, .UK for the United Kingdom, and .US for the United States. Among them, .cn is a top-level domain name dedicated to China, and its registration is managed by CNNIC. We refer to the second-level domain name ending with .cn as domestic domain name. The rules and policies for registering second-level domain names under country code top-level domain names are related to the policies of different countries.

3. New top-level domain name registration is also known as "new top-level domain name". It is an international top-level domain name used since 2001, which was decided by ICANN in November 2000 based on the needs of Internet development. It also includes 7 categories: biz, info, name, pro, aero, coop, and museum. The first 4 are non-restricted domains, and the last 3 are restricted domains. For example, aero must be registered by an aviation company, museum must be a museum, and coop must be registered by a collective enterprise (not controlled by investors, no profit maximization required).

What do common domain name suffixes mean?

Common domain names include .com, .cn, .net, and .org. Different letter combinations can form a new identity, such as baidu.com, iisp.com, gd.gov, and tiexue.net. The former is a representative entity, and the latter is a domain name. The combination of the two forms a new network identity. There are countless combinations of various letter entities + domain names, but the only special thing is that the selected letters and domain names usually have different meanings, allowing users to remember them at a glance, or choose an unconventional domain name to create a different sensory impression in the eyes of users through special letter logos.

.pro, generally created by business owners and professionals in various fields, is mostly used by professionals such as doctors, lawyers, and accountants.
