What CNAME means?
Canonical Name
A Canonical Name or CNAME record is a type of DNS record that maps an alias name to a true or canonical domain name. CNAME records are typically used to map a subdomain such as www or mail to the domain hosting that subdomain’s content.
Can a CNAME record point to other CNAME records?
CNAME records can point to other CNAME records, but this is not considered a good practice as it is inefficient. MX and NS records must never point to a CNAME alias. Domains that are used for e-mail may not have a CNAME record – this can have undesirable results with different mail servers.
Can a CNAME be placed at the root domain?
A CNAME cannot be placed at the root domain level, because the root domain is the DNS Start of Authority (SOA) which must point to an IP address. CNAME records must point to another domain name, never to an IP address.
Can a MX record point to a CNAME alias?
MX and NS records must never point to a CNAME alias. Domains that are used for e-mail may not have a CNAME record – this can have undesirable results with different mail servers. The CNAME Record is typically used alongside other types of DNS Records – A Records and ALIAS Records.
Which is an advanced use case for CNAME?
