What information does the CNAME record hold in a DNS resource record?

Explanation:
A CNAME record defines an alias by storing the alternative name that points to a canonical domain. It doesn’t contain an IP address itself—that's the job of A or AAAA records after you resolve the canonical name. TTL is metadata shared by all DNS records, not the data the CNAME carries. An MX record holds mail server addresses, not host aliases. So a CNAME record’s information is the alternative name for a host that should be treated as an alias for the canonical name.
