ドメインの事前検証：ドメインの一括再検証

ドメインの再検証を1つずつ申請することで余分な時間を費やす必要はありません。ドメインの一括再検証機能を使用して、2～25個のドメインの再検証を一度に申請してください。

Items to note about domain validation:

  • Per industry standards, a domain's validation is valid for 397 days (approximately 13 months).

  • If you order a certificate for a domain while the domain's revalidation is pending, we use the domain's current validation to issue the certificate until that validation has expired.

ドメインの再検証を申請する

  1. CertCentralアカウントの左側にあるメインメニューで、［証明書］＞［ドメイン］の順に進みます。

  2. ［ドメイン］ページで、［認証ステータス］などのフィルターを使用して、再検証するドメインを見つけます。

  3. ［再認証のためにドメインを送信する］ドロップダウンで、［電子メールベースの認証のためにドメインを提出する］を選択します。

    • Revalidation by DNS TXT record

      Go to your DNS provider and create a TXT record. Add a DigiCert-generated random value to the domain's TXT record.

    • Revalidation by email

      An email recipient follows the instructions in a confirmation email sent for the domain. DigiCert can send three sets of DCV emails: Email to DNS TXT contact, Constructed Email, and WHOIS-based.

      • Email to DNS TXT contact

        Place the DNS TXT record on the _validation-contactemail subdomain of the domain you want to validate. The RDATA value of this text record must be a valid email address.

        DigiCert sends an authorization email to the email addresses found in the DNS TXT record on the _validation-contactemail subdomain of the domain you are validating.

      • Email to Constructed Email

        DigiCert sends the authorization email to five constructed email addresses for the domain: admin, administrator, webmaster, hostmaster, and postmaster @[domain_name].

        Before DigiCert can successfully send an authentication DCV email to the domain owner (or domain controller), we must verify that an MX record (a resource record in the Domain Name System [DNS]) exists in the DNS records of the recipient's domain name. The presence of valid MX records enables us to send the authentication email.

      • Email to WHOIS

        DigiCert sends an authorization email to the registered owners of the public domain as shown in the domain's WHOIS record.

        警告

        End of life for the WHOIS-based email DCV method

        The industry is moving away from using WHOIS to identify domain contacts. DigiCert recommends that those using the WHOIS-based Email DCV method update their domain validation processes to use one of the other supported DCV methods as soon as possible. If you still want to use the Email DCV method, use DNS TXT record email contact or Constructed email.

        To learn more about DigiCert’s timeline for the end of life for WHOIS-based email, see our knowledge base article, End of life for WHOIS-based DCV methods.

    • Revalidation by DNS CNAME record

      Go to your DNS provider and create a CNAME record. In the hostname field, enter _dnsauth. Then, add [random_value].dcv.digicert.com in the target host field to point the CNAME record to dcv.digicert.com.
