Subdomains are subdivisions of a domain name that are created by adding a label to the front of an existing domain. They provide a way to organize and structure a domain’s content and services further. Subdomains are commonly used to categorize content, create separate websites, or provide access to specific services while maintaining the parent domain’s identity.

Here’s an example using the domain “example.com” and some possible subdomains:

  1. www.example.com:
    This is one of the most common subdomains and typically points to the main website of the domain.
  2. blog.example.com:
    This subdomain can be used to host a blog associated with the main domain.
  3. shop.example.com:
    This subdomain could be used for an online store or e-commerce section of the website.
  4. mail.example.com:
    Used for hosting email services such as webmail or email clients.
  5. support.example.com:
    A subdomain dedicated to customer support resources or a help center.
  6. forum.example.com:
    Used for hosting an online discussion forum related to the main domain’s topic.
  7. app.example.com:
    A subdomain for hosting a web application or a specific online tool.
  8. images.example.com:
    Often used for serving images and multimedia content.
  9. news.example.com:
    For hosting news articles, press releases, or related content.
  10. events.example.com:
    A subdomain dedicated to event information or calendar.
  11. subdomain.example.com:
    Subdomains can have their subdomains too, creating a nested structure.

Each subdomain can be configured separately with its own content, services, and settings. DNS records are used to map subdomains to their respective IP addresses or other servers. This allows visitors to access different content or services by entering the appropriate subdomain in their browser’s address bar. Subdomains are a powerful tool for organizing and delivering content efficiently, especially for larger websites or organizations with diverse offerings.
