What are subdomains?
A subdomain name is a piece of additional information added to the beginning of a website's domain name. It allows websites to separate and organize content for a specific function — such as a blog or an online store — from the rest of your website.
In the Domain Name System hierarchy, a subdomain is a domain that is a part of another domain. For example, if a domain offered an online store as part of their website example.com, it might use the subdomain shop.example.com.
