What is created when adding branches like canada.mycompany.corp and mexico.mycompany.corp to mycompany.corp?

When branches such as canada.mycompany.corp and mexico.mycompany.corp are added to mycompany.corp, these branches are classified as subdomains. A subdomain is created when a domain is divided into smaller, more specific parts that can function independently but still relate back to the main domain. In this case, "mycompany.corp" serves as the primary domain, while "canada" and "mexico" act as subdomains that help organize different regions or branches under the main corporate identity.

This hierarchical structure allows for better website organization and easier management of different branches, especially in larger organizations that need to provide distinct content or services associated with each specific area. The concept of a subdomain is fundamental in domain name systems, distinguishing it from other domain types, such as root or child domains, which serve different purposes in domain ownership and hierarchy.
