What is a domain name?

"" tell you that a domain name (English: Domain Name), also known as a domain, is the name of a computer or computer group on Internet, which is composed of a string of dot-separated names, which is used to identify the location of the computer (sometimes refers to geographical location) during data transmission.

Because the IP address is inconvenient to remember and cannot display the name and nature of the address organization, people design the domain name and map the domain name and IP address to each other through the domain name system (DNS,Domain Name System), which makes it more convenient for people to access the Internet without having to remember the strings of IP addresses that can be read directly by the machine.

How to register a domain name

"" to tell you that the registration of domain names varies according to different regulatory agencies.

Generally speaking, the administrative bodies of gTLD domain names only formulate domain name policies and do not involve user registration. these institutions will authorize the registration to the approved top-level registrars, which will then be delegated down to other second-and third-tier agents.

The registration of ccTLD is more complex. In addition to following the above-mentioned norms, some countries subcontract domain names to certain companies for management as mentioned above (such as ws in Western Samoa), and there are also regulatory and top-level registrars: (e.g. za, South Africa).

The qualifications required for the registration of various domain names are different. With a few exceptions (such as travel), gTLD generally does not restrict qualifications, while ccTLD often has qualification restrictions and even has to submit physical documents.

The owner of a domain name can be found by querying the WHOIS database; for most root domain name servers, the basic WHOIS is maintained by ICANN, while the details of WHOIS are maintained by the domain registry that controls that domain. Before registering a domain name, you can query the provider through Whois to know the registration of the domain name. For more than 240 country code top-level domain names (ccTLDs), the domain name authority is usually responsible for maintaining the WHOIS.

Generally speaking, .com registered users are companies or enterprises, .org is a corporate legal person, .edu is a school unit, and .gov is a government agency.

When applying for domain name registration, applicants can submit an application form for domain name registration and submit an application for domain name registration to the domain name registrar through domain name registration inquiry, online registration, e-mail, etc., and sign a domain name registration agreement with the domain name registrar.

The application form for domain name registration should include:

Domain name applied for

Hostnames and IP addresses of domain name primary and secondary domain name servers

Name, responsible person, industry, mailing address, postal code, e-mail, phone number, fax number and authentication information of the domain name holder

Domain name technical contact, administrative contact, payment contact, name of the undertaker, name of the organization, correspondence address, postal code, electronic mail address, telephone number and fax number.

The registration of a domain name follows the principle of first application and first registration, and the regulatory body does not conduct any substantive examination on whether the domain name proposed by the applicant violates the rights of a third party. At the same time, each domain name registration query is unique and can not be repeated. Therefore, on the network, domain name is a relatively limited resource, and its value will be gradually valued by people with the increase of registered enterprises.

Effective time of domain name resolution

Generic top-level domain name resolution takes effect within 2 hours, and national top-level domain name resolution takes effect within 24 hours.

How to judge whether the domain name is resolved successfully

Because domain name resolution needs to be synchronized to the DNS root server, and the DNS root server will be refreshed from time to time, the domain name can only be accessed normally after the DNS root server is refreshed. The new resolution usually takes about 10 minutes, with a maximum of 24 hours, and the modified resolution time will be slightly longer. You can use the ping command to see if the domain name is valid. Click start menu > run > enter "CMD" > hit enter, enter the command prompt window, enter "ping your domain name". If the red line is the IP of your host, the resolution is successful.
