What is the use of CNAME record in DNS?
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.
What is the difference between a DNS A record and a CNAME record?
An A record is the actual record. The name is resolved to the corresponding IP address. CNAME records (short for Canonical Name) map your hostname to another hostname. It is useful for pointing many hosts to the same place and updating them easily.
Can DNS have CNAME record?
A CNAME record cannot co-exist with another record for the same name. It’s not possible to have both a CNAME and TXT record for www.example.com . A CNAME can point to another CNAME, although this configuration is generally not recommended for performance reasons.
Is CNAME record important?
CNAME records are used to map one domain to another domain, essentially creating an alias for the second domain. As such, CNAME records are important. They help with whitelabeling Landing Pages in SharpSpring, and they enable DKIM on domains.
Can a CNAME point to an IP address?
All CNAME records must point to a domain, never to an IP address. A frequent misconception is that a CNAME record must always resolve to the same website as the domain it points to, but this is not the case. The CNAME record only points the client to the same IP address as the root domain.
When should CNAME be used?
Use a CNAME record if you want to alias one name to another name, and you don’t need other records (such as MX records for emails) for the same name. Use an ALIAS record if you’re trying to alias the root domain (apex zone), or if you need other records for the same name.
