    CNAME record

    A CNAME (Canonical Name) record refers to the alias record in domain name resolution.
    For example, a server named host.example.com provides both WWW and MAIL services. To make it easier for users to access those services, two CNAME records (www.example.com and mail.example.com) can be added for this server at its DNS service provider, and all requests to access those two CNAME records will be forwarded to host.example.com.
