DNS stores a domain name (domain name) and its corresponding IP address (IP address) table to resolve the domain name of the message. A domain name is the name of a computer or computer group on the Internet. It is used to identify the electronic location (sometimes also the geographical location) of the computer during data transmission. A domain name is a string of dot-separated names, usually including the name of an organization, and always includes a two- or three-letter suffix to indicate the type of organization or the country in which the domain is located.
Domain name types:
First, international domain names (international top-level domain-names, iTDs for short), also called international top-level domain names. This is also the earliest and most widely used domain name. For example, .com .top represents industrial and commercial enterprises, .net represents network providers, .org represents non-profit organizations, etc.
The second is domestic domain names, also known as national top-level domain names (nTLDs for short), that is, different suffixes are assigned according to different countries. These domain names are the country's domestic top-level domain names. More than 200 countries and regions have assigned top-level domain names according to ISO3166 country codes, such as cn for China, us for the United States, jp for Japan, etc.
