Why is my site available on other domains?

Question

Computer networks

I have a website: data-keeper.ru
Right now I got into Google to look for materials on C and by clicking on one of the links it redirects me to (attention): http://fdozz.rewards.teleologies.xyz
FUCK!!! And there is an interface from my site!!! What the hell is this? Who could need me? The site is still under development, it does not bring any profit. The frontend is in a private bitbucket repository. I'm shocked...

Answer 1

Maybe it's someone's some crawler naughty?
Didn't get to see the link :(

Answer 2

It seems to me that this is some new way of spam, I often noticed similar domains in the server logs

Answer 3

all just try to register any domain name on your ip.
if this site works, then your site is in the / var / www folder
or a hedgehog with them, depending on the OS
Why
Because it's like dev zero
All requests that have not received their virtual host go there.
In fact, this folder should contain a file. "buddy you went to the site but it's not here"
But for some reason, many crap sites in this folder. As a result, by registering any A record on this site, you get it in full.
For there is no virtual host, here is the default stub.
There is a virtual host, that's actually the same page.
But if there really is a virtual host and this is another page.
Then check with a ping where this site is, perhaps this is a banal mirror of the server.
Servers can have dozens of them, all depending on the hands-on admins.
