Usa il metodo di convalida DNS CNAME per verificare il controllo sul dominio

Dimostra il controllo sul dominio con un record CNAME DNS

Use these instructions to validate a domain using the DNS CNAME DCV method. In the domains DNS as a CNAME record, add _dnsauth in the hostname field. Then, add [random_value].dcv.digicert.com to the target host field, to point the random value and domain to DigiCert at dcv.digicert.com.

Controlla lo stato del tuo ordine di certificato TLS/SSL e usa il metodo DCV record DNS CNAME per dimostrare il controllo su un dominio nell’ordine. Per ulteriori informazioni, consulta Dimostra il controllo sui domini nel tuo ordine di certificato SSL.

Fase 1: Controlla lo stato del tuo ordine in sospeso

  1. Nel tuo account CertCentral, vai alla pagina dei dettagli N. ordine dell’ordine.

    1. In the left main menu, go to Certificates > Orders.

    2. On the Orders page, in the Order # column, select the certificate's order number link.

      2. On the Certificates page, in the Order # column, select the certificate's order number link.

  2. Nella pagina dei dettagli N. ordine, nella sezione Stato ordine, controlla lo stato di emissione dell’ordine (l’ordine è in attesa del completamento della convalida dominio o organizzazione?).

    When validation is done the Certificate status section no longer appears on the Order # details page.

  3. Under What do you need to do, select the domain's link you want to validate.

  4. In the Prove control over domain window, in the Domain control validation (DCV) method menu, select DNS CNAME Record and then select Save.

  5. Under 2. Add the DigiCert provided token to your CNAME record, in the Order token box, copy the DigiCert-provided random value.

    The random value expires in 30 days.

  6. Create your DNS CNAME record.

    1. Go to your DNS provider’s site and create a new CNAME record.

      For more detailed instructions for creating or updating a DNS CNAME record, try the following resources:

      • Your DNS provider's documentation.

      • DigiCert knowledge base for articles like this one: Create a CNAME Record.

    2. In the hostname field (or equivalent), enter _dnsauth.

    3. In the record type field (or equivalent), select CNAME.

    4. In the target host field (or equivalent), enter [random_value].dcv.digicert.com to point the CNAME record to dcv.digicert.com.

    5. Select a Time-to-Live (TTL) value or use your DNS provider's default value.

    6. Save the record.
