Domains and DNS

Create and edit DNS records with Zone Editor

Reviewed on 4 min read zonas dns registros dns

Before editing, confirm that the domain uses Hostsuar's DNS. If its authoritative zone is with another provider, the change has to be made there. Save the previous values of the records you're going to change.

cPanel's Zone Editor lets you control every record in the domain's DNS zones. Some practical uses:

  • Change the MX (email) records to use an external email provider or anti-spam system.
  • Point the website to an external service while keeping email with us.
  • Set up TXT records required by external services.
  • Point subdomains to other servers with A or CNAME records.

The A record, CNAME records and MX record options are shortcuts for creating these record types, the most common ones.

Manage shows you all the records for a domain, and lets you create, edit or delete any of them.

Available record types:

  • A
  • AAAA
  • CNAME
  • CAA
  • MX
  • TXT
  • DMARC, which generates the corresponding TXT record
  • SRV
  • HTTPS

DNSSEC isn't a record type you create in this list. It is managed from its own interface inside Zone Editor and requires completing the activation with the domain's registrar.

Which types are available depends on the server's version and configuration. Use the records your provider gives you; don't replace a CNAME with another type just because it doesn't appear in the form.

Create a CNAME without duplicating the domain

In the Name field you can enter the subdomain, for example tienda, although cPanel may then show it as tienda.tudominio.com. If you enter the full name, check that the editor hasn't added the domain a second time.

When a provider says @, it means the root domain. cPanel may require or show the full domain name instead.

In Record (the destination), enter the name it should point to, not a URL: use destino.proveedor.com, without https://, slashes or paths.

Common CNAME conflicts

A CNAME can't coexist with A, AAAA, MX, TXT or another CNAME record under the same name. If www already has an A record, you need to edit or remove that record before creating www as a CNAME.

If the name already exists under Domains or Subdomains in cPanel, it will usually have an A record or even its own zone, and it can't also become a CNAME. Check the records and services it uses before changing its structure. Don't delete a hosted domain just to fix a DNS conflict: you may affect the website or email. Contact support if it has its own zone.

The root domain normally shouldn't be made a CNAME because its name shares the SOA, NS, MX and TXT records. To point the root to an external platform, use the A or AAAA records the provider gives you and keep the CNAME for www or another subdomain.

After saving, check the record in public DNS. If it doesn't appear:

  1. Confirm you are editing the zone served by the authoritative nameservers.
  2. Check that the name and destination don't contain the domain twice.
  3. Look for incompatible records with the same name.
  4. Wait for the cache under the previous TTL to expire.

Before you save or delete

Check the full name, type, destination, MX priority and TTL. A verification TXT record is usually added without touching the other TXT records; for SPF and DMARC you need to review the existing record so you don't duplicate the policy. Don't delete the MX records when setting up an external website.

If you've been given several records, you can prepare them with the DNS assistant. For a domain without hosting, see the client area zone editor.
