Can multiple domains have the same CNAME?
Can I set up multiple A and CNAME records? While you are allowed to create multiple A and CNAME records for the same destination, you can set only one A and CNAME record per source or host name.
How do you add CNAME and alternate CNAME records in the DNS for your domain?
Add a CNAME record to your domain’s DNS records
- Go to your domain’s DNS records.
- Add a record to your DNS settings, selecting CNAME as the record type.
- Return to the first window or tab and copy the contents of the Label/Host field.
- Paste the copied contents into the Label or Host field with your DNS records.
What is a DNS CNAME record used for?
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 domain have two A records?
The value of an A record is always an IP address, and multiple A records can be configured for one domain name.
How does the CNAME record work in DNS?
A DNS resolver receives the request and finds the Authoritative Name Server that holds the DNS Zone file with DNS records for the “example.com” domain. The DNS request is resolved and the CNAME record is returned to the client.
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.
How to use different DNS servers for different domains?

What’s the difference between an alias and a CNAME record?
An A Record maps a hostname to one or more IP addresses, while the CNAME record maps a hostname to another hostname. Difference between ALIAS and CNAME The ALIAS Record, like CNAME, also maps a hostname to another hostname. However, the ALIAS Record makes it possible to have other DNS records on the same hostname, while CNAME does not.
