Top-Level Domain Vs Subdomain: Know The Difference

top level domain vs subdomain

When it comes to organizing and identifying websites on the Internet, domain names play a crucial role. A domain name is a unique address that users type into their web browsers to access a particular website. Within the domain name structure, there are two important components: top-level domains (TLDs) and subdomains. 

A top-level domain is the last part of a domain name, such as .com or .org, indicating the website’s purpose or country of origin. Subdomains are divisions that precede the TLD, allowing further categorization of a website. For example, in, “blog” is the subdomain.

3. Ownership and Control: 

TLDs are controlled by domain name registries, which manage the registration and distribution of domain names globally. Subdomains, on the other hand, are created and managed by the owner of the main domain, giving them the ability to organize and structure their website’s content as they see fit.

4. Unique Identification: 

Each TLD is unique and serves as a distinct identifier for websites. Subdomains, however, are not unique globally and can be reused across different domain names. For example, multiple websites can have the subdomain “blog” (,

5. Branding and Website Structure: 

TLDs are commonly used for branding and establishing the overall identity of a website. Subdomains, on the other hand, are used to categorize and organize specific sections or services within a website (e.g.,,
