What is Domain Registration?

Domain name registration is a method used in the Internet to solve the problem of address correspondence. According to the China Internet Network Domain Name Management Measures, domain name registrars and domain name registrars need to verify whether the domain name proposed by the applicant violates the rights of third parties and the true identity of the applicant. Every second-level domain name registration in the same top-level domain name is unique and cannot be repeated, but the second-level domain names in different top-level domain names can be the same. For example, the second-level domain name baidu can be registered in .com or Registered in .cn, you can also register in .xyz and many other top-level domain names, and each domain name plays the same role. Therefore, the domain name is a relatively limited resource on the Internet, and its value is gradually valued by people with the increase of registered enterprises and individual users.

1. It can contain English letters (az, case-insensitive), numbers (0-9), and half-width connector "-" (that is, a horizontal line). Spaces and special characters (such as!, $, & ,?Wait);
2. "-" cannot appear continuously, cannot be registered separately, and cannot be placed at the beginning or end;
3. You can register up to 63 characters. ^[1]

Domain names are often likened to real estate. On the basis of this domain name, you can build a website (such as a residential or commercial building) and the highest "quality" domain name. Like hot real estate, they often carry significant value, usually because of their online brand building. Potential for use in

Domain names can be divided into different levels, including top-level domain names, second-level domain names, third-level domain names, and country code domain names.

Domain Name Registration

The domain name system is a core service of the Internet. As a distributed database that can map domain names and IP addresses to each other, it can make people more convenient to access the Internet without having to remember IP strings that can be directly read by machines. .

Domain registration deletion period

1. International domain names can be submitted for renewal within 30 days of expiration but not guaranteed; redemption period of 30-60 days after expiration can be redemption fee for redemption, but there is no guarantee of success. The day is the deletion period (pendingDelete). This state can only be registered after waiting for deletion.

2. If the international domain name expires and enters the redemption period (REDEMPTION PERIOD), you can only choose to handle the redemption or wait for the domain name to be released and re-register.

Registration expiration, renewal and redemption rules for domestic top-level domains (such as: .cn):

According to the requirements of the China Internet Network Information Center (CNNIC), from December 20, 2007, the renewal rules for CN English domain names will be implemented.

Corresponding adjustments:

The CN English domain name has not been renewed for expiration, and the domain name will enter the renewal period. During this period, your domain name may be suspended from being resolved until you successfully renew it. Renewable 30 days after cn expires. If the renewal period is still not completed, the domain name will enter a high-priced redemption period, and the status of the domain name will become "pendingDelete". Operations such as information modification, transfer, and analysis cannot be performed. If you still want the domain name, you need to pay the domain name redemption fee in accordance with regulations. If the domain name is not redeemed during the redemption period, the deletion period will be 60-75 days after the redemption period ends, and the domain name will be deleted.

Domain names with different suffixes have different meanings. The most popular domain names can be divided into international domain names and domestic domain names. The main difference between the two is the division of domain names and management agencies. To explain what is an international domain name and what is a domestic domain name, let's start with the domain name system. There are three types of top-level domain names in the domain name system on the Internet: category top-level domain names, geographical top-level domain names, and new top-level domain names.

Domain name registration

1. For domain names with websites. (Doesn't need to be registered for domain without website)

Domain name registration

2. Submit relevant website information to the Ministry of Information Industry.

The purpose of domain name registration is to prevent illegal website operation activities on the Internet and to combat the spread of bad Internet information. If the website is not registered, it may be shut down after being investigated and punished. In accordance with the spirit of the "Administrative Measures for the Recording of Non-operating Internet Information Services" reviewed and approved by the Twelfth Ministerial Conference of the Ministry of Information Industry of the People's Republic of China, the provision of non-operating Internet information services within the territory of the People's Republic of China should be filed! Without filing, it is not allowed to engage in non-operational Internet information services within the territory of the People's Republic of China. The unregistered website will be fined or closed. Recording refers to reporting the cause to the competent authority for the record. From the perspective of administrative law, in practice, it is mainly the provisions of the Legislative Law and the Regulations on the Recording of Regulations.

Domain name registration

How can I see the contents of my website after registering a domain name? In a technical term, it is called "domain name resolution". As explained in the explanation of related terms, the domain name and the URL are not the same. After the domain name is registered, it only indicates that you have the right to use the domain name. If you do not perform the domain name resolution, then the domain name cannot play its role. The resolved domain name can be used as the suffix of the e-mail address, or it can be used as the URL to access your own website. Therefore, the necessary link for the domain name to be used is "domain name resolution". A domain name is a set of address translation systems that is specially established for the convenience of memory. To access a server on the Internet, it must ultimately be implemented through an IP address. Domain name resolution is the process of re-converting a domain name to an IP address. A domain name can only correspond to one IP address, and multiple domain names can be resolved to one IP address at the same time. Domain name resolution needs to be done by a dedicated domain name resolution server (DNS). Domain names translate into IP addresses, and domain names are a world. In a distributed hierarchical directory service of thousands of servers, the namespace that manages the Internet is divided into so-called areas, each of which is managed by an independent administrator. For local requirements-such as within a company's network-it is a stand-alone operation that also works from the Internet's DNS.

Domain registration resolution principle

To understand why domain name resolution takes so long, you need to understand the domain name resolution process and the role of the DNS server.

Every computer on the Internet is assigned an IP address, and data transmission is actually performed between different IP addresses. Including the computers we use when surfing the Internet at home, an IP address is also assigned after connecting to the Internet. This IP address is dynamic in most cases. In other words, if you turn off the modem and turn on the Internet again, your Internet access provider will randomly assign a new IP address.

The web server is essentially a computer with Internet access, but it is more suitable as a server in configuration, and it is placed in the data center to maintain a low temperature and low dust environment, while being secure. These servers use a fixed IP address to connect to the Internet. A domain name is resolved to a certain server, and the webpage file is placed on this server, then the user's computer knows which server to go to obtain the webpage information of this domain name. This is done through a name server.

When a visitor enters a domain name in the address box of the browser, or clicks a link from another website and arrives at the domain name, the browser sends a domain name request to the user's Internet access provider. Domain name database, see what the DNS server for this domain name is. Then go to the DNS server to fetch DNS records, that is, to obtain which IP address this domain name points to. After obtaining this IP information, the server of the access provider goes to the server corresponding to this IP address to grab the webpage content, and then transmits it to the requesting browser. ^[3]

Domain name registration resolution settings

A (Address) record is used to specify the IP address record corresponding to the host name (or domain name). Users can point the website server under this domain name to their web server. At the same time, you can set the second-level domain name of your domain name.

You must go to the domain name management interface of the registrar to set it to the correct, effective and stable DNS. It may take 12-72 hours for DNS modification at the registrar to be reflected on the root server. The full name of the TTL value is "Time To Live". In short, it means that the DNS record is cached on the DNS server.

MX records are also called mail routing records. Users can point the mail server under this domain name to their own mail server, and then they can control all the mailbox settings by themselves. Just fill in your server's IP address online, and your domain name All the e-mails below are transferred to your own mail server.

CNAME records are alias records. This record allows you to map multiple names to the same computer. Usually used for computers that provide both WWW and MAIL services. ^[4]
