All traffic to and from Imagine Math is transmitted using the highest levels of encryption available, and, unless noted in Imagine Math's Technical Specifications document, will only go to the thinkthroughmath.com domain.
In order to improve application performance, Imagine Math uses the Amazon Cloudfront Content Delivery Network for static files such as images, PDFs, and the like. Our Cloudfront DNS aliases are:
- https://content.thinkthroughmath.com is an alias for https://duni8xfq5pwee.cloudfront.net and is used for the math content images used in our product.
- https://math.imaginelearning.com (IP address 220.127.116.11) is used to redirect users to https://lms.thinkthroughmath.com.
If you are having trouble loading images or styles in Imagine Math, you may find that whitelisting https://d1u1lnfihlxz3u.cloudfront.net and https://duni8xfq5pwee.cloudfront.net will solve the problem. These subdomains are only for Imagine Math use and no non-Imagine Math content will be served from them.
Imagine Math leverages the Amazon Web Service Cloud to help us quickly and easily scale to meet performance and capacity needs. We understand that schools need to ensure the privacy and security of their networks and their students, which is why we ensure that all DNS hostnames for Imagine Math services use the *.thinkthroughmath.com pattern.
Some firewalls and security devices cannot filter by domain name, only by IP. Since Amazon Web Services is a massive platform, the IP address ranges that Imagine Math could be deployed on are very broad. Although we strongly recommend using DNS for traffic filtering, If you need to whitelist IP ranges for Imagine Math, these are the ranges of IP addresses Imagine Math could use.
Additionally, we strongly encourage you to add https://notify.bugsnag.com to your whitelist. This service is used for error reporting and troubleshooting.
