Yes, of course, you are right. That's the correct behavior but what if someone pings example3.com and finds it's ip address and then hits the ip address and sees example1.com instead of example3.com?
My question is is there a way to control via ispconfig or manually from the configuration of bind9 or httpd or it is just chosen randomly. I just want to know if there is a way. I know the right way to access a website.
