I have a server and want to run my own name server service. Now I have set it up already and it works not, but I do not know where the exact settings are stored.

On my server I use Plesk. When I edit DNS settings there I think it is stored in named.conf. Named is installed on the server, and BIND.

Now I also have a panel from my registrar. This is separate from my server.

Both places I can add the normal MX,A,CNAME, etc records.

Now where is the best way to place this settings. Currently I have the same records on both places, on the server and at the registrar panel.

I am correct to just add all the records at the registrar panel, and remove everything from within PLESK, and just don't run DNS on my server, because it is already done in the registrar panel.

Or should I add the records in both places.
