CNAME Lookup
Follow a domain’s canonical name records.
A CNAME record makes one hostname an alias for another: look up the alias and DNS hands back the target's records instead. A CNAME lookup shows which target a hostname currently points to.

How CNAME Lookup works
What it does
Follow a domain’s canonical name records.
What you get
Canonical hostnames returned by the domain’s CNAME records.
Live data sources
The target is sent to a network provider. Results include their source; timeouts and unavailable data are clearly marked.
What if a check cannot finish?
Confirm your input and try again. A timeout, blocked request, or unavailable provider is not proof that a domain is broken. Internet measurements and third-party services have limits.
CNAME Lookup — frequently asked questions
Can I put a CNAME on my root domain?
Not in standard DNS — the root must hold SOA and NS records, which a CNAME cannot coexist with. Many providers offer ALIAS, ANAME or CNAME flattening as a workaround.
Why does my CNAME return an IP address instead of a hostname?
The resolver followed the chain for you and returned the target's address record. The CNAME is still there; the lookup simply resolved through to the end.
Can a CNAME point at another CNAME?
Yes, and it works, but every extra hop adds a lookup. Long chains slow resolution and some providers reject them outright.
