Connecting a 1&1 domain to your Squarespace site

If you purchased a domain from 1&1 and want to keep it registered with them, you can connect it to your site by following this guide. In this process, you'll change a few settings in your 1&1 account. After completing these steps, your domain will stay registered with 1&1, but it will connect to your Squarespace site. Before you begin, review our requirements for connecting a third-party domain.

Tip: We recommend transferring your domain to Squarespace instead of connecting it. Here are some reasons why you might want to transfer your domain: 

  • You can move all aspects of managing it to your Squarespace account so you won't need to pay for it through a third party.
  • Your domain could qualify for one free year of hosting.
  • Squarespace can help with any issues with your domain directly.

Your domain must be eligible to transfer. Learn more about the differences between transferring and connecting or get started with a transfer here.

Navigating your 1&1 account

The screenshots in this guide show how a 1&1 account looks if you're in the United States, using a MyWebsite package, and have access to the beta version of their DNS panel. If you're in a different country, or using a different plan, your experience might be slightly different.

To follow this guide, be aware of the following in your 1&1 account:

  • When logging into 1&1, ensure you’re logging into the Control Panel, and not the Customer Shop.
  • Ensure you can access your Domain Center. You can usually get there by first clicking Home in your left sidebar.
  • If you’re still having trouble navigating your account, contact 1&1’s support team or visit their documentation.

Step 1 - Open the Domains panel

In your Squarespace Home Menu, click Settings, and then click Domains.

You can also press the ? key while any panel is open and search domains.

Step 2 - Link your domain

Click Use a Domain I Own. Enter the full domain name you’re linking in the Domain Name box, and then click Continue.

Click Connect From Provider.

Note: If you see a message that says "This domain is already connected to another Squarespace site," check any other Squarespace sites you manage to determine where the domain is connected, then disconnect it from that site. For help logging into the correct site, visit Managing multiple sites.

Select 1&1 from the drop-down menu, if it's not already selected.

Click Connect Domain. You'll see a message letting you know that the connection to your domain is in progress. Click Okay to continue.

sqsp_-_connecting_in_progress.jpg

A new panel will open with the records you need to enter in your 1&1 account to connect your domain to Squarespace. Keep this panel open for your reference.

Step 3 - Log into 1&1

In a new browser tab or window, go to www.1and1.com and log into your Control Panel. In the Domains menu, click Manage domains.


1_1_-_click_manage_domains.jpg

In the My Domains list, find the domain you’re linking to Squarespace. Click the to the right and select DNS.

1_1_-_choose_dns.jpg

You'll now copy the records from the Squarespace Domain panel so your 1&1 domain correctly links to your Squarespace site.

Note: Don't delete MX records during this process. MX Records connect your email address, and deleting them could interfere with your email service.

Step 4 - Add the first CNAME

In the first line of your Squarespace DNS Settings, copy the unique code that appears directly below the Host column. The unique code is a random string of numbers and letters that must point to verify.squarespace.com.

sqsp_-_first_cname.jpg

In your 1&1 DNS settings, adjust the filter at the top of screen to Display All Records.

1_1_-_choose_display_all_records.jpg

Above your existing records, click Add Record.

1_1_-_add_record.jpg

On the next page, enter the data for the unique CNAME:   

  1. From the Type drop-down, select CNAME.
  2. In the Host Name box, paste the unique code from Host column of the Domains panel.
  3. In the Points to box, enter verify.squarespace.com
  4. Leave the TTL option as 1 hour
  5. Click Save.

1_1_-_first_cname.jpg

You should now have a CNAME with your unique Host code pointing to verify.squarespace.com.

Note: If you don't add this CNAME, or if it's entered incorrectly, the domain will unlink from your site after 15 days. If this happens, you can start over to reconnect the domain.

Step 5 - Add the second CNAME

In the second line of your Squarespace DNS Settings, www appears directly below the Host column. This record must point to ext-cust.squarespace.com.

Note: Your Squarespace DNS settings might also display a second www Host with the Record AAAA. This is a nameserver record from 1&1 that you'll delete from your 1&1 settings later in the process, but you can ignore it when adding your Squarespace records to 1&1.

sqsp_-_second_cname.jpg

In your 1&1 DNS settings, ensure that your filter is still set to Display All Records and then click Add Record.

On the next page, enter the data for the unique CNAME:  

  1. From the Type drop-down, select CNAME.
  2. In the Host Name box, enter www
  3. In the Points to box, enter ext-cust.squarespace.com
  4. Leave the TTL option as 1 hour
  5. Click Save.

1_1_-_second_cname.jpg

You should now have a CNAME with www pointing to ext-cust.squarespace.com.

I see an error message when I try to save this record

After clicking Save for the second set of CNAME records, you may see an error message that says “A CNAME record can only be set for one subdomain.”

If you see this message, click Cancel and review the following in your existing 1&1 DNS Settings:

  1. Ensure the filter at the top of the page is set to Display All Records.
  2. Delete any other records with host www by clicking the to the right of the record and choosing Delete record. Confirm by clicking Delete again on the next page.
  3. Sometimes changes in 1&1’s DNS settings take time to propagate. Wait at least one hour, then refresh your DNS setting using your browser’s refresh button.
  4. If you’re still having trouble, contact 1&1’s support team and ask if you have other records that could be preventing you from adding the new CNAME.

Step 6 - Add A records

In the last four lines of your Squarespace DNS Settings, you'll see four IP addresses in the Required Data column. Using the steps below, create four A Records in 1&1 matching these values.

sqsp_-_a_records.jpg

In your 1&1 DNS settings, ensure that your filter is still set to Display All Records and then click Add Record.

On the next page, enter the data for the first A record:

  1. From the Type drop-down, select A.
  2. In the Host Name box, enter @
  3. In the Points to box, enter 198.185.159.144
  4. Leave the TTL option as 1 hour
  5. In the preview section, click Do not add DNS record for www. The preview will adjust to a crossed-out preview www record.
  6. Click Save
Note: If you see an error message saying “The service will be disabled,” ensure you’ve completed #5 in the steps above. If you don’t click Do not add DNS records for www, 1&1 will attempt to add a record that overrides the second CNAME.

1_1_-_first_a_record.jpg

Repeat this process three more times using the following IP addresses, ensuring that you disable the additional www record with each record:

  • 198.185.159.145
  • 198.49.23.144
  • 198.49.23.145

You should now have a four A records pointing to the following IP addresses: 

  • 198.185.159.144
  • 198.185.159.145
  • 198.49.23.144
  • 198.49.23.145
Note: If you have existing A Records, edit any with a Host Name @ so the Value matches the values above. If you see other A Records in your account that don’t match what’s shown in this guide:
  • Host: @ or blank - Delete only if it doesn't match what’s shown in this guide.
  • Host: Mail or Email - Don’t delete. This connects to your email address. Deleting it could interfere with your email service.

Step 7 - Delete AAAA Records

Delete any existing AAAA records in your 1&1 DNS settings, as these might conflict with your new records pointing to Squarespace.

  1. Ensure that your filter is still set to Display All Records
  2. Next to each AAAA record, click the to the right of the record and choose Delete record.
  3. Confirm by clicking Delete again on the next page.

Step 8 - Refresh

After changing your records, return to your Squarespace DNS Settings and click Refresh below the records. 

The Current Data column in the panel will start to update and show if your records are entered correctly. It can take up to 72 hours for this information to process.

To go the previous panel, click the arrow in the top-left corner.

sqsp_-_refresh_or_go_back.jpg

Step 9 - Wait and test

If all records are entered correctly, your domain will connect to your site within 24 hours. At times, it can take up to 72 hours. Visit the Domains panel at any time to check your progress.

When the domain is correctly linked, the domain will appear in the Domains panel with a Connected label.

Troubleshoot with the DNS record checker

If we detect that your records weren’t set up properly, your domain will appear in the Domains panel with the message Can’t verify domain ownership.

To troubleshoot, use the DNS checker tool in the Domains panel to see the exact CNAME and A Records to fix with your domain provider.

Click the domain in the Domains panel, and then click DNS Settings. For detailed instructions, visit Checking your domain mapping records.
