Connect Squarespace DNS to your domain
Before starting, make sure that your domain's Nameservers are pointing to Crucial. The easiest way to do this is to check your domain on ozdns.com.au The first nameserver should be either nssyd01.crucial.com.au or nssyd01.aumanaged.com or nssyd01.clusterdns.net
Step 1 - Log in to https://www.squarespace.com/login
Next click on SETTINGS
Then click on Domains
Now click on CONNECT A THIRD-PARTY DOMAIN
Step 2 - Enter your domain name and hit CONTINUE
Select Other as your domain provider and hit CONNECT DOMAIN
Click OKAY on the next screen
Here is the important information, your DNS settings.
Step 3 - Keep that page open. Now open another window and log in to cPanel (click here for a guide)
Find the Zone Editor and log in
Step 4 - For the first record, you'll want to add an A Record. Open the Squarespace page for the details of the record, then go back to the Zone Editor and click on the menu option for A Record.
Add the Host (@ just means the domain name, in this example: yourdomain.net.au) and the Required Data into the Address field.
Note: You do not need to add the TTL as the server sets this automatically.
Now go ahead and do this for the other 3 A Records.
Step 5 - Next, add the first CNAME Record. Make sure to open the Squarespace page for the record.
Note: The domain name will automatically be added to the Host record. This is fine and won't have any negative effects. Also, you do not need to add the TTL as the server sets this automatically.
Step 6 - Click on Manage
Look for an A Record for your domain (ignore subdomains like cpanel.yourdomain mail.yourdomain etc) that does not match the 4 records you added previously. Delete this.
Now look for the www CNAME record (www.yourdomain.net.au in this case) and delete that record.
Step 7 - Scroll up to the top of the screen and click on Domains
Now add the last CNAME record listed in on the Squarespace page.
Note: cPanel will automatically add your domain name to the www. Also, you do not need to add a TTL as the server sets this automatically.
Step 10 - Back to Squarespace. Hit refresh every few minutes. The DNS settings are normally live within 60min but they can take up to 24hrs. Once all the fields are marked in green as Correct, hit TEST CONNECTION and your site is ready and pointed to Squarespace.
