How do I prevent other domains from using my droplet public IP?
I recently created a droplet and then assigned a floating IP to it. I configured the floating IP in my DNS manager and everything works as expected. However, I noticed that my website was getting traffic from other domains, and when I use the DNS checker to see what IP they were connected to, to my surprise it was the public IP of my droplet. How do I prevent this in future and even more important, how do I fix this?
