My School Filter is Blocking a Resource

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.

  • * — netTrekker product
  • * — authentication services
  • * — Dictionary and Read Aloud features within netTrekker are provided by TextHelp

We suggest allowing the following domains, but these are not required for netTrekker operation.


  • * — Some video content for support and training is hosted with YouTube

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.
