Types of Domains: TLD, Second-Level and Third-Level Domains
Top-Level Domain (TLD)
The Top-Level Domain, also known as a TLD or extension, is the final part of a domain name and is used to identify either a geographical region or a type of activity.
When the TLD corresponds to a specific country or region, it is referred to as a ccTLD (country code top-level domain). Common examples include .it for Italy, .fr for France, and .es for Spain.
On the other hand, a gTLD (generic top-level domain) is used to indicate a general category, often related to an organization's area of activity. A typical example is .com, which is widely used by commercial entities.
Second-Level Domain
The second-level domain appears directly before the TLD and typically identifies a person, company, brand, product, or service.
In the example www.utixo.net, the part utixo is the second-level domain, representing the company that offers its services through the website. In essence, the second-level domain conveys the identity and content of the site.
Third-Level Domain (Subdomain)
The third-level domain, also known as a subdomain, designates a specific section or functionality within the main domain.
For example, in mail.utixo.net, the mail subdomain points to a dedicated area of the site, typically used for a specific service like email management.
