To point your domain to Squarespace, please follow these steps:

1. Sign in to your Dynadot account.
2. Select "My Domains" from the left-side menu bar and click "Manage Domains" in the drop-down.
3. Check the box next to your domain name(s) and click on the "Action" button.
4. Choose "DNS Settings" from the "Action" list.
5. On the DNS Settings page, select the "Dynadot DNS" setting from the top drop-down menu.
6. You will need to create two CNAME records. Scroll down to the "Subdomain Records (optional)" section and select "CNAME" from the drop-down menu. Enter your unique Squarespace code (the unique code that appears directly below the Host column in your Squarespace account) in the 'Subdomain' field. In the 'IP Address or Target Host' field, enter verify.squarespace.com.
7. Remain in the "Subdomain Records (optional)" section and enter "www" as the next subdomain. Select "CNAME" from the drop-down and then enter ext-cust.squarespace.com in the "IP Address or Target Host" box. Do not enter your actual domain name.
8. Next, you will enter the "A" records. Scroll up to the "Domain Record (optional)" section and select "A" as your record type. Enter 198.185.159.144 in the "IP Address or Target Host" box.
9. Repeat this for the other three Squarespace IP addresses - 198.185.159.145, 198.49.23.144, and 198.49.23.145
