In the world of the internet, every website has a unique address, which is known as a domain name. A domain name is a string of letters, numbers, and hyphens that serves as a substitute for the complex and difficult-to-remember IP address, allowing users to access a website easily. For example, “www.example.com” is a typical domain name that points to a specific digital IP address of a server. A domain name is the brand identifier of a company on the internet and also the first impression that users have of your website.
The core components of a domain name
To understand a domain name, it is first necessary to break down its structure. A complete domain name consists of multiple levels, which are read from right to left, with each level having a progressively lower rank.
top-level domain
The top-level domain is the last part of a domain name, located on the far right. It is mainly divided into two categories: generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs). Generic top-level domains include .com (for commercial organizations), .org (for organizations), .net (for internet services), etc., and are the most widely used around the world. Country-code top-level domains, such as .cn (for China), .us (for the United States), .jp (for Japan), etc., represent specific countries or regions.

secondary domain
A secondary domain is the part of a domain name that users can directly register and customize, located to the left of the top-level domain. For example, in “example.com,” “example” is the secondary domain. It represents the core of a brand name, company name, or project name, and is the most valuable and creative element of the domain name.
subdomain
Subdomains are a further subdivision of second-level domains and are located to the left of the second-level domain name. The most common subdomain is “www”, which typically represents a World Wide Web (WWW) service. Users can also create other subdomains, such as “blog.example.com” for a blog or “shop.example.com” for an online store, in order to distinguish different functional sections of a website.
How to choose and register a suitable domain name
Choosing a good domain name is the first step to the success of a website. A good domain name should be short and easy to remember, relevant to your brand, and easy to spell and pronounce.
After selecting the desired domain name, it is necessary to perform a search and registration process through a domain name registrar. Well-known registrars worldwide include GoDaddy and Namecheap, while in China, services are provided by providers such as Alibaba Cloud and Tencent Cloud. The registration process is generally quite simple: search for the domain name on the registrar’s website, select an available one, add it to the shopping cart, and complete the purchase along with the required identity verification.
During registration, the fee is usually paid on an annual basis. Users can choose to register for 1 year, 3 years, 5 years, or even a longer period. Make sure to pay attention to the domain name renewal costs and the auto-renewal settings to prevent your domain name from being taken by someone else if it expires and is not renewed.

Key Steps in Domain Name Selection and Website Construction
Registering a domain name is just the first step; to make the domain name accessible to your website content, you need to complete a series of key configurations.
domain name resolution
A domain name itself cannot directly open a website; it needs to point to a server that stores the website’s files. This process is called domain name resolution. You will need to log in to the management interface of your domain name registrar or DNS service provider and add an “A record” or a “CNAME record” for your domain name, directing it to your server’s IP address or an alias. It usually takes a few minutes to a few hours for the resolution to take effect and for the changes to be synchronized globally.
Purchase hosting space
The server host is the location where all the files for a website, such as the website’s programs, databases, and images, are stored. Depending on the website’s requirements, you can choose between a virtual host, a cloud server, or a dedicated server. After purchasing the host, you will receive a server IP address, which is the target that domain name resolution needs to point to.
Bind a domain name
In the host management panel, there are usually functions such as “Domain Name Binding” or “Add Website.” You need to enter the domain name that you have already resolved here. This way, when users visit that domain name, the server will know which file in the corresponding website directory to retrieve and display.
The complete process for registering a domestic domain name in China
In mainland China, if a website service is provided using domestic servers, it is required by law and regulations to undergo ICP (Internet Content Provider) registration with the Ministry of Industry and Information Technology. This is a legal and mandatory process.
The entity responsible for the registration can be either an individual or a organization. For individual registration, a valid ID card is required; for organizational registration, additional documents such as a business license and a organization code certificate are needed, along with the ID information of the person in charge. Additionally, you must prepare the registration service number (issued by the server provider) and a website authenticity verification document.

The entire process can be roughly divided into several stages: First, submit a registration application and fill in the required information through the server provider’s backend. Next, the organizer’s information is verified; in some cases, a photo of the background is required. After that, the server provider conducts a preliminary review and submits the application to the regulatory authority. Finally, the Communication Administration Bureau conducts an official review, and if the application is approved, a registration number will be issued. The entire process typically takes 10 to 20 working days.
After the registration is successful, you need to display the obtained ICP registration number at the bottom of the website’s home page and provide a link to the official website of the Ministry of Industry and Information Technology. Websites that fail to complete the registration process may have their access services shut down by their server providers in accordance with the law.
summarize
Domain names are the foundation of the internet world, serving as the bridge that connects users to the vast array of online resources. The process involves understanding their composition, carefully selecting and registering a domain name, binding it to a server through DNS resolution, and finally completing the necessary registration procedures in mainland China. Mastering this knowledge not only helps you launch your website successfully but is also crucial for safeguarding your brand assets and ensuring the legal and compliant operation of your business. Proper management of your domain name is essentially protecting your “home” in the digital world.
FAQ Frequently Asked Questions
Can individuals register domain names?
Yes, individuals can definitely register domain names. Whether you want to use them for a personal blog, a portfolio website, or for learning and testing purposes, you can purchase domain names from various domain registrars around the world. During the registration process, you simply need to provide your real personal information and complete the corresponding identity verification.
.What is the difference between .com and .cn domain names?
.“.com” is an internationally recognized top-level domain with a long history and high recognition, and is generally considered the default choice for commercial websites. “.cn” is China’s national top-level domain, governed by Chinese laws and regulations. If your website is primarily targeted at the Chinese market and uses domestic servers, registering a “.cn” domain may provide a stronger sense of local relevance, and the registration process may be smoother. However, there is no difference between the two domains in terms of technical functionality.
Can a domain name be changed after it has been registered?
The core part of a domain name, namely the registered second-level domain name (such as “example”), cannot be changed once it has been successfully registered. If there is a spelling error or if you are not satisfied with the name, you can only register a new domain name.
However, you can modify the administrator contact information associated with the domain name, the DNS resolution server addresses, and the IP address (A record) that the domain name points to at any time. All these operations are performed through the domain name management backend.
Can a website be accessed if its domain name has not been registered with the authorities?
It depends on the location of your website server. If your website server is located outside mainland China (for example, in Hong Kong, the United States, etc.), then when you point the domain name to these servers, you generally do not need to undergo the domestic ICP (Internet Content Protection) registration process, and your website can be accessed normally.
If your server is located within the Chinese mainland, then according to the regulations, the domain name must be registered with the ICP (Internet Content Provider) registration system administered by the Ministry of Industry and Information Technology. Only after passing the registration review can the website be accessed normally. Otherwise, the server provider may block access requests for that domain name.
