If you purchased your domain from one of these domain registrars, click for specific instructions:
1&1 / IONOS

Step 1 - Add your domain to your B12 account

1. Log in to the B12 Editor.

2. From the Home menu, click Domains.

3. If this is your first domain, click Get Started.

If you've added a domain previously, click Add domain.

4. Enter your domain, starting with www.

  • Check the Make this my primary domain box if you want this domain considered your official domain by search engines. We accomplish this by automatically adding a canonical tag to all pages of your website pointing to your primary domain.

  • Check Enable email sending for this domain if you want to be able to send emails through B12, but you are using another email service to receive emails. See more information here.

  • Check Enable email forwarding for this domain if you would like to create a custom email address. See more information here.

5. Click Sync domain.

6. Copy the CNAME Record Value by clicking the Copy button next to it.
Note: Your CNAME Value will end in

Keep this tab open so you can reference these values, if needed, and finish your domain setup.

Step 2 - Edit your Domain's Records in your Domain Registrar 

1. In a new tab, log in to your domain registrar (you can check to find out who your domain registrar is).

2. Find your domain in your account. 

3. Find your domain's DNS records. Every domain registrar is different, but the records can be found under the following terms: Manage DNS, DNS Zone Editor, Control Panel, DNS Settings, Host Records, etc. 

4. Delete any existing A Records with the host/name @ or
Delete any CNAMEs with the host/name www.

5. Add an A Record with these values:

  • Set the Host/Name to: @
    (if @ doesn't work, set it to your domain name, formatted as 

  • Set Points to or Value to:

  • If you see TTL, set it to 1 Hour

6. Add a CNAME with these values:

  • Set the Host/Name to www
    (if www doesn't work, set it to your domain name, formatted as )

  • In Points to or Value: [paste the CNAME value you copied from the B12 Editor.]

  • If you see TTL, set it to 1 Hour

7. Click Save or Update if that is an option.

8. Return to the B12 Editor and click Check status.

If your records were added correctly, each record will show as Connected with a green light within a few minutes to a few hours.

7. Click Publish or Save.

Note: It may take a few hours for your Domain to show as Connected in the Editor, and it may take 24-48 hours for your B12 website to appear on your domain.
