CNAME (Canonical Name Record)

A CNAME (Canonical Name) record is a type of DNS record that links one domain name to another. It acts like a alias or nickname, directing traffic from a secondary domain to the primary or main domain. For example, if you have "www.example.com" and want "blog.example.com" to point to the same website, a CNAME record can be set up so that "blog.example.com" redirects to "www.example.com." This simplifies management, allowing you to update the main address without changing all associated links. CNAMEs are useful for organizing and maintaining consistent access points across different domain names.
