A subdomain is an additional part of a domain name placed to the left of the main domain. For example, in blog.nic.ua, the blog part is a subdomain of nic.ua.
In simple terms, a subdomain helps split a website into separate sections or services: for example, shop.example.com for a store, support.example.com for support, or mail.example.com for email. This is useful for project structure, administration, and navigation.
A subdomain is the part of an address placed before the main domain. For example, in blog.site.com, the word blog is a subdomain. It is used for separate website sections or services.
In most cases, yes. A subdomain is usually a third-level domain, such as blog.example.com. However, technically there can be more levels (for example, dev.blog.example.com).
A subdomain is useful for separate services and sections: blog, store, knowledge base, support, user account, email, or a staging/test version of a site. It helps organize functions within one domain.
