CNAME Lookup

Check whether a hostname is an alias (CNAME) and follow it to its canonical target.

No CNAME on an apex/bare domain (e.g. example.com) is normal — CNAMEs live on subdomains.

How to read the result

A CNAME points one name at another canonical name, forming an alias chain that resolvers follow to the final A/AAAA record. Apex/bare domains cannot have CNAMEs (they need SOA/NS), so 'no record' there is expected.

Example

www.example.com CNAME → example.com

FAQ

No CNAME found — is that an error?

Usually not. Most apex domains and direct hosts simply have A records instead of aliases.

Can a CNAME chain be long?

Yes, CDNs often chain several CNAMEs before the final address record.

CNAME vs A record?

A gives an IP directly; CNAME gives another name that must be resolved further.
