Definition
A CNAME (Canonical Name) record is a type of DNS (Domain Name System) record that maps one domain name to another, allowing multiple domain names to point to a single IP address. It provides an alias for an existing domain, enabling easier management of multiple domain variations.
Function
The main function of a CNAME record is to enable users to access a website using different domain names while resolving to the same IP address. This is particularly useful for setting up subdomains or redirecting domains (such as www.example.com to example.com) without needing to change the original domain’s IP address. CNAME records help simplify domain management, improve branding, and enhance the user experience by allowing for easier access to the same resources.
