What is the structure of a domain name? What rules and meanings lie behind it? A domain name is not only a website address, but also part of a brand image. Today, we'll introduce the general format of a domain name.
I. Basic Structure of a Domain Name
The basic format of a domain name can be divided into several main parts. Typically, a complete domain name consists of the following parts:
1. Protocol Prefix
Although strictly speaking, the protocol prefix is not part of the domain name, it is a common prefix when accessing a website. The most common protocols are "http://" or "https://". "https" indicates that the website uses a secure transmission protocol, which encrypts data transmission between the user and the website.
2. Subdomain
The subdomain is the most important part of a domain name, usually representing the website's name or brand. For example, in "abc.Example.com", "abc" is the subdomain. This part is usually used to identify a specific organization, brand, or individual; choosing a good subdomain is crucial for brand promotion.
3. Top-Level Domain (TLD)
The top-level domain is the last part of the domain name, usually used to indicate the domain type or country. For example, ".com" is the most common commercial domain name suffix, while ".cn" represents a domain name from China. The choice of top-level domain can affect users' trust and impression of a website.
II. Domain Name Naming Rules
After understanding the basic structure of a domain name, we also need to pay attention to some naming rules. These rules help ensure the validity and recognizability of the domain name:
1. Character Restrictions
Domain names can only contain letters (az), numbers (0, 9), and hyphens (-). However, hyphens cannot be at the beginning or end of the domain name, nor can they be used consecutively. For example, "example123.com" is valid, while "-example.com" is invalid.
2. Length Restrictions
The overall length of a domain name is usually limited to 63 characters, while a complete domain name (including the top-level domain) cannot exceed 253 characters. Choose short and easy-to-remember domain names to facilitate user access and sharing.
3. Avoid Special Characters
When choosing a domain name, try to avoid using special characters (such as @, $, etc.) and spaces. These characters are not allowed in domain names and will confuse users.
4. Brand Protection
When registering a domain name, it's best to choose a name that aligns with your brand and consider registering multiple related top-level domains to prevent others from registering similar domains. This helps maintain your brand image and avoid potential legal disputes.
