Whitelisting Domains for Demme Learning Digital Toolbox

This guide explains how to whitelist domains to ensure smooth access to Demme Learning’s online resources and video playback. Whitelisting trusted domains bypasses restrictive firewalls while maintaining a secure environment.

What is Whitelisting?
Whitelisting is the process of allowing specific websites or domains through your firewall or content filter. It ensures that your network grants access to trusted resources necessary for an optimal learning experience.

Domains to Whitelist
To ensure seamless access, whitelist the following Fully Qualified Domain Names (FQDNs) in your firewall or content filter:

Core Domains

• demmelearning.com
• digital.demmelearning.com
• mathusee.com
• spellingyousee.com
• analyticalgrammar.com
• writeshop.com

CDNs (Content Delivery Networks)

• jwpcdn.com
• jwplayer.com
• jwpsrv.com
• jwpltx.com
• cloudfront.net
• akamaihd.net
• fastly.net
• cdnjs.cloudflare.com

Additional Resources

• google-analytics.com
• googletagmanager.com
• kit.fontawesome.com
• use.typekit.net
• ssl.p.jwpcdn.com

Example Firewall Configurations
Below are some examples to illustrate how to whitelist domains based on common firewall platforms:

1. For SonicWall Firewalls
   • Navigate to Firewall Settings > Access Rules.
   • Add an Allow Rule for each domain in the list (e.g., demmelearning.com).
   • Use the wildcard format for subdomains: *.jwplayer.com.
2. For Cisco Firewalls
   • Go to Security Services > Content Filtering.
   • Under Permitted Domains, add each FQDN from the list above.
   • Save and apply the configuration.
3. For Home Routers
   • Access your router’s admin panel (usually at 192.168.1.1 or 192.168.0.1).
   • Locate the Parental Controls or Content Filtering section.
   • Add the domains in the Allowed Websites section.

Best Practices for Whitelisting

• Include Subdomains: Use wildcard entries (e.g., *.jwplayer.com) to capture all related subdomains.
• Dynamic IP Handling: Avoid relying on static IP addresses since CDNs often use dynamic IP ranges. Focus on domain-level whitelisting instead.
• Test and Verify: After whitelisting, test functionality by accessing videos and pages on restricted devices.
