Subdomain

A subdomain is a division or extension of the main domain that allows you to organize and separate sections of a website efficiently. Subdomains act as independent addresses under the same main domain, and are commonly used to separate areas of a website, such as online stores, blogs, or user panels.

For example, if the main domain is ejemplo.com, a subdomain could be blog.ejemplo.com. Here, blog is the subdomain that points to a specific section of the website, which in this case would be a blog. Subdomains are managed through DNS (Domain Name System) and can be directed to different servers or directories, allowing them to function almost like completely independent domains.

Using subdomains is a common practice because it helps structure large sites better and can help optimize SEO (Search Engine Optimization) by providing clarity about the specific content of the subdomain, and they generally do not incur additional costs beyond the main domain.
