DNS
CNAME Chain Checker
Follow every alias to its destination.
UNDERSTAND THE RESULT
What this check tells you
The chain is followed for up to 12 aliases. Missing terminal addresses and loops are reported separately from DNS query failures. A valid chain does not prove that a hosting provider has accepted your custom domain.
A snapshot, with context
Every report includes its check time. DNS caches, CDN edges and server configuration can change. Repeat a check after a fix and compare the actual records or responses.
