DNS

CNAME records

Make one name an alias of another — and the rules that stop a CNAME from being saved.

1 min read Updated

A CNAME record makes one name an alias for another. Wherever the target points, the alias follows. It is how you connect a subdomain to a service that gives you a hostname rather than an address — a shop platform, a landing-page builder, a mailing tool.

Add a CNAME record

  1. Open the domain's DNS records: Domains → the domain → Manage DNS.
  2. Under Add a record, choose CNAME.

  3. Name — the subdomain to alias, such as www or shop.
  4. Value — the hostname it should follow, such as yourdomain.com or shops.example-platform.com.
  5. Choose a TTL and click Add record.

The two rules

Important

A CNAME must be the only record on its name. If shop already has an A, MX or TXT record, remove it before you add the CNAME.

Important

The domain itself can't be a CNAME. yourdomain.com always has nameserver records, so it can't also be an alias. Use an A record for the bare domain, and a CNAME for www.

Example
