Recently, some newbies who want to invest in domain names have consulted me about some issues regarding the purchase of top-level domain names. Today, I will tell you what top-level domain names are.

Top-level domain names are relative to second-level domain names. Domain names are composed of two or more strings. The rightmost string is the top-level domain name or the first-level domain name. Top-level domain names are generally divided into three categories: national top-level domain names, international top-level domain names, and new top-level domain names.

1. National top-level domain names

For example, a country is called a national top-level domain name ccTLD. Currently, more than 200 countries have allocated top-level domain names. Only the domain names of the country can be used, and domain names of other countries cannot be used. Of course, we can also understand ccTLD as a basic rule.

2. International top-level domain names

International top-level domain names are referred to as gTLDs. For example, com represents a commercial organization, and not all domain names are commercial organizations. org represents a non-profit organization.

3. New top-level domain names

There are many new top-level domain names, and they are referred to as gTLDs. Among them, .reg represents red and .men represents people.
