Question

Stop people from accessing through IP.

DNS Ubuntu 18.04

I have a droplet with the public ip and ubuntu running apache.

I have cloudflare for ssl.

People access my website through domain.com
and it is secured.

But people can also access it through the public ip

How do I stop that?

Hello friend!

You can block all traffic to the web server in your firewall, and then allow traffic from these IP ranges:

https://www.cloudflare.com/ips/

This will ensure that your web server can only be reached through CloudFlare.

Kind Regards,

Your link shows bunch of ips. What do you actually do with them to stop accessing IP other than your own domain?
Is there any more information on this somewhere?
Someone is using my IP address to host his sub-domain.
