Step 1.

Login to your Rebel account and select Domain Manager.

Step 2.
Click directly on your domain name to access the domain editing page.

Step 3.
On the domain editing page, select the DNS tab.

Scroll down to Manage Advanced DNS Records and click on Advanced DNS Manager. 

If this section is not available, your domain may be set to Use Third Party Hosting with another provider's DNS. If this is the case, you will need to either make these changes in your DNS provider's account or park your domain on Rebel nameservers.

To park your domain on Rebel DNS, please go to Nameserver Information and from the dropdown menu choose Park with Rebel (Default). 

Click Save Changes in this section.

Click on the domain name again to open the domain editing page, select the DNS tab, scroll down and click New Advanced DNS Manager.

Step 4.
Remove the two A-records that have the Host as yourdomain and www.yourdomain by clicking the down arrow to the right of Edit, and clicking Delete. 

Step 5.
Click the button to Add New Record. 

Leave the Record Type set as A. Leave the Host field blank (this will default to being your domain name), and in the Points To field enter the first of the IP addresses Squarespace has provided you (indicated in the chart above). Click the green button to Save.

Step 6.
Repeat Step 5 until all four Squarespace A-Records are created. 

Step 7.
Click the button to Add New Record and set the Record Type as CNAME. In the Alias field, type your unique string (jumble of letters and numbers) that Squarespace has given you (available in your Squarespace account), and under Points to put verify.squarespace.com. Click the green button to Save.

Step 8.
Click the button to Add New Record again, and set the Record Type as CNAME. In the Alias field, type www and under Points to type ext-cust.squarespace.com. Click the green button to Save.

If your domain was already set to Park with Rebel, Forward Domain, or Host with Rebel, these records should take about 1 hour to propagate. If your domain was previously set to Use Third Party Hosting, updates can take up to 24-48 hours to propagate worldwide, though we find it's typically much closer to 6-12 hours.
