Common Use Cases for CNAME Records:

www Subdomain: Typically, a CNAME record is used to point the www subdomain (e.g., www.example.com) to the main domain name (e.g., example.com). Alias Domains: You can use CNAME records to create alias domains (e.g., alias.example.com) that point to your main website (example.com). Subdomains for Services: CNAME records can be used to point subdomains to specific services hosted elsewhere. For example, a CNAME record for mail.example.com might point to your email provider’s domain name. By understanding CNAME records, you can effectively manage your domain names and simplify how users access your website or other resources.
