netTrekker offers safe, academically relevant, educator reviewed resources. It is recommended that schools modify their content filter and "whitelist" any site with a referrer from the netTrekker and associated domains.
The following domains must be allowed for proper netTrekker operation.
- *.knov8.services — Knovation authentication services
- *.speechstream.net — Dictionary and Read Aloud features within icurio are provided by TextHelp
We suggest allowing the following domains, but these are not required for minimum netTrekker operation.
- *.knovationlearning.com — Our corporate address
- *.vimeo.com — Some video content for support and training is hosted with Vimeo
Because each filtering device is different, please check with your filter vendor on updating. There should be an interface with the filter that allows you to list the websites or referrer information for the sites you want to allow.
Web technology and the way we access the internet is always evolving. As new versions of web browsers are released, Knovation will review the impact on our products and work to meet user expectations by testing for compatibility in order to create the best experience possible.
We recommend using web browsers for the supported operating systems listed below. Please use our System Check to ensure that your web browser up-to-date.
Apple OS X 10.8 and above for Desktops
- Apple Safari, versions 6.0 and above
- Google Chrome, versions 35 and above
- Microsoft Internet Explorer, versions 9 and above
- Mozilla Firefox, versions 29 and above
netTrekker may also work in older versions of the browsers listed, or in other browsers not listed, but these will not be tested and are not recommended.
Microsoft Internet Explorer has the tendency to introduce new functionality which may have impact on previous capabilities. Knovation will review the impact of Internet Explorer releases and test support by the start of each school year.

Security Notice About Apple QuickTime
Apple will no longer be providing security updates for QuickTime for Windows, leaving this software vulnerable to exploitation. Computers running QuickTime for Windows will continue to work after support ends. However, using unsupported software may increase the risks from viruses and other security threats. Potential negative consequences include loss of confidentiality, integrity, or availability of data, as well as damage to system resources or business assets. The only mitigation available is to uninstall QuickTime for Windows.
New versions of Windows since 2009 have included support for the key media formats, such as H.264 and AAC, that QuickTime 7 enabled. All current Windows web browsers support video without the need for browser plug-ins.
Note that this does not apply to QuickTime on Apple Mac OS X.

While netTrekker and many of the resources currently included work well on mobile devices, desktop devices are the preferred environment for accessing netTrekker as the user interface has not been specifically optimized for the mobile environment.
Using netTrekker with an Apple iPad
Using the native functionality of iOS 7, we have been able to optimize some features such as Dictionary and Read Aloud when using netTrekker from an Apple iPad. To take advantage of this you must use the Apple Safari browser on iPad models 2 and above with iOS 7 and above.
Additional information about using netTrekker with the Apple® iPad can be found in our guide Make the Most of netTrekker on Your iPad.
Using netTrekker with a Google Chromebook™
The Google Chromebook does not natively support the sound file format currently used for the Read Aloud feature within netTrekker. However, you are able to add the functionality of the Read Aloud feature by adding the SpeakIt! extension from the Chrome Web Store.
Accessing Flash-Based Content
Approximately 15% of the resources currently included in netTrekker are developed with Adobe Flash and are not natively compatible with some mobile devices, such as the Apple iPad. We have worked to provide netTrekker as an approved solution through the Puffin Academy web browser, the fastest mobile browser for K-12 education to support the use of Flash-based content. The Puffin Academy web browser is available for Apple mobile devices, as well as Android-based devices.
