DNS problem ?

[NoExecute]

Hi guys 🙂

Got somewhat of  a  rookie problem.

Rented a new VPS,  based on debian 9, and hooked it up to my DNS.
My primary site / domain is www.labet.dk, the server is downloads.labet.dk.
The  strange thing is, if I try to ping it on downloads.labet.dk, I get a response from the right IP, but DNS , it shows up as mail.darrenmusic,com.
When I log in, and run a netstat -a, this is the output

root@downloads:~# netstat -a

I cant seem to find any services configured to mail.darrenmusic.com, so right now, Im really lost.

Any thoughts would be really welcome...

Sorry for asking rookie questions 🙂
