To build your own website on the internet, having a domain name is the first step – it’s like your unique address in the digital world. However, the process from having the idea to successfully launching the website involves several steps, including purchasing the domain name, setting up domain name resolution, and actually building the website itself. This article will break down the entire process of building a website from scratch in detail, helping you to complete each step clearly and efficiently.
Basic Knowledge of Domain Names and Selection Strategies
Domain names are crucial identifiers on the internet, consisting of a series of characters separated by dots, used to locate and identify computers. A carefully chosen domain name is essential for brand building and online promotion.
The structure and composition of domain names
A complete domain name usually consists of several parts. Taking “www.example.com” as an example, “.com” is the top-level domain, which indicates the category or country/region of the domain name. “example” is the second-level domain; this is the core part that can be registered by users and also serves as the main identifier for the brand. “www” is the third-level domain, which is typically used to point to a specific server service, such as a website server. What users mainly purchase and own is the combination of the “second-level domain” and the “top-level domain”.

How to choose a suitable domain name
When selecting a domain name, there are several key principles to follow. Firstly, the domain name should be as short, easy to remember, and easy to spell as possible, avoiding the use of obscure words or complex spellings. Secondly, it is best if the domain name is highly relevant to the brand, business, or website theme, as this will help users to remember it and search engines to understand its meaning. Additionally, it is advisable to choose common top-level domains such as .com, .cn, .net, etc., as they are more widely recognized and trustworthy. Finally, it is essential to check whether the domain name is already in use before registering it to ensure that no one else’s trademark rights are being infringed.
Detailed Process for Domain Name Registration and Purchase
After selecting the desired domain name, the next step is to complete the purchase through a domain name registrar. This process is usually done online and is very convenient.
Choosing a reliable domain name registrar
A registrar is a company that is authorized to provide domain name registration services. When choosing a registrar, you should consider factors such as their reputation, price transparency, customer service quality, and the ease of use of their management interface. There are many well-known registrars both domestically and internationally, offering a range of services including domain name lookup, registration, renewal, and management in one place. It is recommended to choose a large registrar that provides reliable DNS resolution services and excellent after-sales support.
Complete the registration and real-name authentication
After searching for and confirming the availability of the domain name on the registrar’s website, add it to your shopping cart and complete the purchase. You will need to create an account and provide accurate registration information for the domain owner. According to the regulations of the China Internet Information Office, all national top-level domain names (such as .cn) registered in China, as well as international domain names (such as .com) used to connect to domestic servers, require real-name verification. You will be prompted to upload identification documents for either an individual or a business. The domain name will only become officially active after the verification process is completed. Please make sure that the information provided is true and valid, as it is crucial for the ownership and security of the domain name.
The core principles and configuration methods of domain name resolution
After purchasing a domain name, it alone does not allow the website to be accessed. It is necessary to use domain name resolution to point the domain name to the IP address of the server where the website content is stored.

How DNS Resolution Works
When a user enters a domain name in their browser, the browser sends a query to a recursive DNS server. The recursive server starts by querying the root domain name server and then proceeds to query the top-level domain name servers and authoritative domain name servers in turn, until it obtains the IP address corresponding to that domain name. This process is known as DNS recursive resolution. Only after the IP address is obtained can the user’s request be correctly routed to the website server. The authoritative DNS records for the domain name you have purchased are usually managed by your domain name registrar or a professional DNS service provider.
How to set up domain name resolution records
You need to add resolution records in the domain name management backend. The most common type of record is the A record, which directs a domain name directly to an IPv4 address. For example, you can use an A record to point the “@” or “www” host to your server’s IP address. Another common type is the CNAME record, which points a domain name to another domain name, allowing for alias functionality, which is often used when connecting to CDN (Content Delivery Network) or cloud service platforms. Additionally, MX records are used for email server resolution, while TXT records are commonly used to verify domain name ownership. After the configuration is completed, it takes some time for the DNS (Domain Name System) to be updated globally; this process can range from a few minutes to several hours and is known as DNS propagation.
Practical Steps for Website Construction and Domain Name Binding
Once the domain name resolution is in place, the final step is to bind the domain name to the website program or hosting space that you have already developed, so that the website can be launched officially.
Select a website hosting method.
Based on your technical skills and requirements, you can choose different methods for building a website. For beginners or small and medium-sized enterprises, using a mature website building platform or a content management system (CMS) is an efficient option. If you have your own server, you can install web service software to deploy your website yourself. Regardless of the method you choose, you will need a website hosting environment that can be accessed via a public IP address or an alias.
Complete the server or space binding process.
In the website hosting platform or server management panel, locate the options for domain name binding or virtual hosting configuration. Add the domain name you have already resolved to the list of bound domains. This tells the server that when users access the website using that domain name, it should serve the content from the specified directory. Make sure that the domain name is also correctly set up in your website’s configuration to ensure that internal links and resource references function properly.
Conduct a comprehensive test before going live.
After the binding process is complete, it is crucial to conduct a thorough test. Enter your domain name in a browser to check whether the website opens correctly, and ensure that the page layout, images, and links are displayed properly. Use online tools to verify whether the DNS resolution has taken effect globally. Test how the website appears on different devices. Finally, you can try submitting the website to search engines to check for any server security configuration issues that may affect accessibility.

Once you master the entire process, whether you’re creating a personal blog or a corporate website, you can plan and implement your projects more systematically, ensuring that your website launches successfully on the internet.
FAQ Frequently Asked Questions
Do you permanently own a domain name after registering it?
Domain names are not owned permanently but are rented on an annual basis. What you own is the right to use the domain name during the registration period. The registration period typically ranges from 1 to 10 years, and it is necessary to renew the domain name in a timely manner before it expires. If you forget to renew it, the domain name will go through a redemption period and will eventually be deleted and made available for re-registration. In that case, you may lose the right to use it.
How long does it usually take for domain name resolution to take effect?
It takes some time for the changes to domain name resolution to take effect; this process is known as DNS propagation. Generally, the effect becomes visible within a few minutes to a few hours. However, due to the different caching mechanisms of DNS servers around the world, it may take up to 48 hours for the changes to be fully implemented in some areas. Please be patient after making the configuration changes.
Can a domain name point to multiple websites?
A domain name usually points directly to a main website. However, by using different subdomains, one domain name can be used for multiple websites or services. For example, “www.example.com” can point to the main site, “blog.example.com” can point to a blog, and “shop.example.com” can point to an online store. Each subdomain can have its own resolution records set independently, directing users to different servers.
What is the difference between a domain name and a virtual host?
Domain names and virtual hosts are two completely different concepts. A domain name is the address of a website, used to locate it on the internet. A virtual host (or server) is the physical storage space and operating environment where the website’s files, databases, and other content are stored. Only when a domain name is resolved to the IP address of the corresponding virtual host can users access the website content through that domain name.
What should I do if someone else has registered my domain name?
If the domain name you are interested in has already been registered by someone else, you can first try to contact the current owner through the “WHOIS” query service provided by the domain registrar and ask if they are willing to sell it. If they are not interested in selling, you can consider registering a variant with a different domain extension, or creating a new, unregistered domain name by adding prefixes or suffixes, or using abbreviations.
