TXT レコードでのドメイン所有権の証明

この記事では、Cloud Identity で利用するドメインの所有権を TXT レコードを使用して証明する方法について説明します。

Why verify?

After you verify that you own your domain, you can start using your Google service, such as G Suite, G Suite Essentials, or Cloud Identity. If you have G Suite, you can start using Gmail, Google Drive, and all the other services included with your G Suite account.

Note: If you purchased your domain when you signed up for G Suite, you don't need to verify. If you are in a G Suite trial, you must verify your domain within the first 9 days of your trial period. 

Verify your domain for your Google service

You verify your domain through your domain host (typically where you purchased your domain name). Your domain host maintains settings called DNS records that direct internet traffic to your domain name. For details, see Identify your domain host.

Google gives you a TXT verification record to add to your domain host's DNS records. When Google sees the record exists, your domain ownership is confirmed. The verification record does not affect your website or email.

Add a TXT verification record (any domain host)

Note: The administrator that gets the verification record needs to complete the verification process. The verification records are unique to each administrator, so one administrator cannot finish a domain verification that was started by another. 

Step 1: Get your unique verification record

If you already signed up for G Suite but didn't complete the setup process, you can pick up where you left off.

  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. Open the setup tool and click Verify.

    A red circle highlights the "Activate" option in the domain verification section.

  3. Click Continue to verify your domain with a TXT record. You can also click Switch verification method if you need to use another method.

    A red circle highlights the Continue button at the bottom of the Here

  4. Click Copy to copy your unique verification record.

    A red circle highlights the Copy button next to the TXT verification record.

Step 2. Go to your domain's DNS records

  1. In a second browser window or tab, sign in to your domain host account. For details, see Identify your domain host.
  2. Go to your domain's DNS records. The page might be called something like DNS Management, Name Server Management, Control Panel, or Advanced Settings.
  3. Select the option to add a new record.

Step 3. Add the verification record to your domain host

  1. For the record type, select TXT.
  2. In the Name/Host/Alias field, enter @ or leave it blank.
    Your host might require you to enter your domain, which looks like example.com, into this field. Your other DNS records might indicate what you should enter.
  3. In the Time to Live (TTL) field, enter 86400 or leave the default.
  4. In the Value/Answer/Destination field, paste the verification record you copied in step 1.
  5. Save the record.

Note: If you see a warning message about changing your DNS settings, disregard it. Adding the TXT record won't damage your website or DNS settings.

Step 4: Tell Google to verify

  1. Return to the setup tool in the Admin console and click Verify.

    A red circle highlights the "Activate" option in the domain verification section.

  2. Click Continue, then scroll to the bottom of the next page. Click Verify my domain.

    A red circle highlights the Verify My Domain button on Step 5. Add your TXT Record page of the wizard

Next steps (G Suite only)

After you verify your domain, you can set up Gmail with G Suite. Keep the Admin Console and your domain host site open in your browser. In a new tab or window, open detailed instructions for setting up Gmail with your host.
