DNS records connect your site with third-party tools and services while helping users reach your website and email addresses. They're essential for domain ownership authentication and enhanced security.

When to Update DNS Records

You can modify DNS records in Squarespace if you:

• Own a Squarespace-managed domain
• Have connected a third-party domain via name server connection

Note: For domains connected via DNS connection, edit DNS settings through your third-party provider.

Accessing DNS Settings

1. Open Domain dashboard
2. Select domain name
3. Click [DNS Settings]

Types of DNS Records

Common DNS record types include:

• A and AAAA (IP address mapping)
• ALIAS and CNAME (domain aliases)
• DKIM and SPF (email authentication)
• MX (mail servers)
• TXT (text information)
• CAA (certificate authorization)
• HTTPS (secure connections)

Custom TTL Settings

Time To Live (TTL) determines record cache duration:

• Accessible via dropdown menu when editing records

Deleting DNS Records

2. Scroll to Custom Records
3. Hover over record

Remember to always backup existing DNS configurations before making changes and consult with your service provider for specific record requirements.
