How to disable a domain that links to my IP?

Question

Domain name market

We recently created a job aggregator service work-at.me and after some time noticed transitions from a strange site in the metric, opened the site and found that it was a mirror of my site at igm-host.tk . I can't figure out how it happened at all and how to deal with it. I have a virtual server, a dedicated IP, what could be the problem?

Answer 1

server { 
listen 80;
listen anything another;
server_name igm-host.tk; 
return 200 "Smeni A-zapis, ublydok";
}

Answer 2

Set up the web server so that only your site and only by name are returned.
A friend takes your site to ip address 82.146.55.81

Answer 3

No, it's the norm.
It is enough to create a CNAME record.
