But my work's VPN is in AWS, and HN and Reddit are sometimes helpful...

Not sure what my point is here tbh. The internet sucks and I don't have a solution

Tricky to get a list of all cloud providers, all their networks, and then there are cases like CATO Networks Ltd and ZScaler, which are apparently enterprise security products that route clients traffic through their clouds "for security".

Because crawlers would then just use a different IP which isn’t owned by cloud vendors.
