Here's the concise, value-focused rewrite:

Point your Squarespace domain to a third-party site or create a subdomain by modifying DNS settings. Follow these steps to properly configure your domain.

Before You Begin:

• Ensure your domain uses Squarespace name servers
• Have the destination site's URL and IP address ready
• Note that embedded domains cannot be specified

Point to a Third-Party Site:

1. Add CNAME Record:

• Navigate to Domain Dashboard → DNS → DNS Settings
• Delete Squarespace Defaults
• Add Custom Record: Type = CNAME
• Host: www
• Data: Enter provider's URL
• Save changes

2. Add A Record:

• Add another Custom Record: Type = A
• Host: @
• Data: Enter provider's IP address
• Save changes

Create and Point a Subdomain:

1. In DNS Settings:

• Add Custom Record
• Choose CNAME (for URL) or A (for IP)
• Host: Enter subdomain name (e.g., "blog")
• Data: Enter provider's URL or IP
• Save changes

For Big Cartel, ClickFunnels, SiteGround, SmugMug, Systeme.io, or Zoho:

1. Add CNAME Record:

• Delete Squarespace Defaults
• Create CNAME record with provider's URL
• Host: WWW

2. Add Domain Forwarding:

• Go to Website section
• Add forwarding rule
• Source: @
• Destination: Full URL
• Keep SSL on
• Choose redirect type (301 or 302)

Troubleshooting:

• Allow 24-72 hours for changes to take effect
• Test in incognito mode
• For DNS conflicts, remove third-party domain links first
• Ensure name fields have 4+ characters
• If changes don't work after 72 hours, disable DNSSEC, reset name servers, then re-enable DNSSEC

Changes typically propagate within 24-72 hours. Test the connection using an incognito browser window.
