Can you have a CNAME and A record with the same name?
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.
What is difference between A record and CNAME?
These are the main differences: The A record maps a name to one or more IP addresses when the IP are known and stable. The CNAME record maps a name to another name. The ALIAS record maps a name to another name, but can coexist with other records on that name.
How do I check my CNAME record?
The CNAME lookup is done directly against the domain’s authoritative name server, so changes to CNAME Records should show up instantly. Also called a canonical name records, they act as aliases, pointing to another DNS name. For example, you might have a CNAME record docs.example.com, which points to ghs.google.com.
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.
Which is a better alternative to CNAME or NS1?
Linked Records – a Smart Alternative to CNAME. NS1’s next-generation DNS platform supports a proprietary DNS record type called a Linked Record. NS1.
What’s the difference between a and CNAME in DNS?
For subdomains which will resolve to the same address, you do have a choice between A and CNAME records. The practical difference between A and CNAME records is that CNAME will cause an additional lookup (to resolve the alias to the canonical name) which is not incurred with a direct A record.
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.
