Definition
A CNAME record creates a DNS alias that points one hostname to another hostname.
What does it mean in practice?
For domains, this term affects registration, transfer, DNS operation, website availability and e-mail routing.
A practical Hostilla.pl example
A domain can be registered correctly while its website or e-mail still fails because delegation or zone records point elsewhere. Use CNAME record as the starting point, then compare registry data, authoritative DNS and the service destination.
What should you check?
- domain status, registrar and expiry date
- authoritative name servers and current delegation
- A, AAAA, CNAME, MX and TXT records required by the service
- TTL values and answers from authoritative and caching resolvers
