Feature request for any service like this: Let "me" know if it is a school, so I know that I am probably dealing with minors, a public environment and a firewall. Of course, you need to do the work (rDNS to start) to identify the schools.

I love the speed of the responses!

I work for IPinfo. We have higher level IP category information on our website for free.

We categorize ASN and companies/organizations based on 4 categories: ISP, Education, Hosting and Business. This ASN level categorization are done mainly from WHOIS and other public internet records.

We don't sub-categorize by schools, university, public research institutions, k-12 etc. The reason is accuracy. Even though I can understand the possible methods for doing this, the issue is that it can not be done reliably at scale.

As a data provider, from our end we hope to provide the highest possible accuracy and vouch for the service we provide. For this level of classification, we will generally request users to say what data they need from us, and we try to help them come to a solution that they have to build on their own. They can do whatever classification they want to do based on their personal level of tolerance for accuracy.

IPINFO.io has that info, but I too would like to have this information in a free service.

University's and post secondary educational institutions can have k12 schools attached especially if they study education or are isolated

Seems like schools should opt-in by submitting their IP address/range
