I'm running a Samba4 domain (AD style) with the internal DNS backend.
Most things are working great but I have an issue : the DC's IP (I have two of them) are automaticaly added as @ IN A entries
I want to set it to another host (mainly for web access which should point on my reverse proxy). I can add other @ IN A entry, but if I remove the ones corresponding to the DC, they are automatically added back a few minutes later. How can I avoid that ? AFAIK, DC are not required to be listed in the @ IN A entry

How can I handle this, and prevent the DC's IP to be added back ?

@ IN A   # This is the entry I've added, which should be the only one
@ IN A   # This is the IP of the 1st DC, which is added back if removed
@ IN A   # This is the IP of the 2nd DC, which is added back if removed
