Remove or lockdown bind

Help! (Home for newbies)

I’m moving to a new Debian 12 server and am a newby with bind9.

Bind is installed by default, but I use my registrar’s name servers for all domains. I switched off bind as a feature. But I noticed that my server still functions as a name server for the outside world.

  1. Should I just uninstall bind?

  2. Or make it accesible to local access only by editing named.conf.options to make stuff safer?

listen-on port 53 { 127.0.0.1; };
listen-on-v6 port 53 { ::1; };
allow-query { localhost; };
allow-recursion { localhost; };

  1. Or just forget about it and let it run as I always did? Maybe it does important stuff I am not aware off?

You can simply stop and disable the BIND service. It’s not very large just sitting on disk.

Once the feature is disabled, it probably can be removed. I think it’s a soft dependency for Virtualmin.
