I read an article by David Robinson: https://stackoverflow.blog/2017/02/15/how-do-students-use-stack-overflow
He filters questions posted by users at educational institutions identified by their ISP. I would like to do something like this for the company I work at.
Unfortunately, the appropriate query is not given. I tried to figure it out using http://api.stackexchange.com/docs/questions but cannot find the appropriate fields in the filter selection.
