Hostnames and domains are integral to the internet’s domain name system (DNS). However, subdomains have become increasingly vital for website owners to serve the growing needs of their audiences.
As a child of the parent domain, subdomains are a separate but useful part created to offer specialized features or functionality.

When internet users go to navigate to your website, the domain name system (DNS) uses domain pointing and lookups, eventually translating the domain name into the IP address of the host server…
