Second-level Domain Support on NetSuite CDN 2025.1

Starting in NetSuite 2025.1, you can now host second-level domains on the NetSuite content delivery network (CDN). This enhancement allows semi-independent websites to leverage the performance and security benefits of the CDN while simplifying SSL certificate management. Here’s a closer look at what this means and how to implement it effectively.

Key Features of Second-level Domain Hosting

• Domain-Validated SSL Certificates: NetSuite can generate SSL certificates that are validated for your second-level domains, providing added security for your web services.
• Automatic Updates: The CDN automatically keeps your SSL certificates up to date, minimizing administrative overhead and reducing security risks associated with expired certificates.
• Similar Rules to Third-Level Domains: The procedures and requirements for hosting second-level domains on the CDN mirror those in place for third-level domains, ensuring a consistent user experience.

Important Requirements and Conditions

To successfully host your second-level domain on the NetSuite CDN, ensure you adhere to the following guidelines:

• CNAME Flattening: Maintain the use of CNAME flattening for your second-level domains, similar to the setup used for third-level domains. This is crucial for DNS resolution and to ensure the domain points correctly to the CDN.
• DNS Configuration: Follow NetSuite’s guidelines outlined in the help topic "Point Your Domain Name at Your Domain (DNS Settings)" to complete your DNS setup.

Who This Affects

This feature impacts the following roles and modules within NetSuite:

• Administrators: Responsible for domain setup and configuration.
• Developers: Engaged in integrating and customizing modules with second-level domain support.
• IT Managers: Overseeing SSL certificate management and security protocols.

Key Takeaways

• NetSuite 2025.1 introduces support for second-level domains on its CDN.
• Automatic SSL certificate management minimizes manual administrative tasks.
• Ensure proper DNS configuration, including CNAME flattening, for successful implementation.
• Best for businesses needing independent branding and security with their web properties.

Embracing these capabilities can enhance the security and functionality of your NetSuite environment, allowing for a more robust online presence.
