A CNAME, or Canonical Name, maps one domain to another. For instance, if you own two websites, “menaccessories.com” and “menstuff.com,” and you set up a CNAME to point “menstuff.com” to “menaccessories.com,” visitors who enter “menaccessories.com” in their browser will be able to view the content from “menstuff.com.” Essentially, it allows one domain to serve as an alias for another, simplifying domain management and content accessibility across multiple websites without duplicating content. This can help streamline web traffic to a primary site while maintaining different domains.
