Hostingraja

This gives a partial listing of all the sites hosted directly on Hostingraja: https://myip.ms/view/hosts/40988277/hostingraja_org.html

These are the Cloudflare IP range that shouldn't be blocked by my webhost for proper working of my websites via Cloudflare: https://www.cloudflare.com/ips/

My webserver is placed behind Cloudflare for security. This special URL tells from which data center someone is being served: https://wiki.ekvastra.in/cdn-cgi/trace

And this link tells, from the same location and connection, what is the POP that the ISP (and Cloudflare) is going to: https://1.1.1.1/cdn-cgi/trace

For emailing pdf functionality I have enabled allow_url_fopen for quiz.ekvastra.in with my hosting provider. This feature cannot be enabled at user level.
