Webserver TCP port 53 is open or closed?

Hello,

By default the webserver TCP port 53 is open or closed?
It is unsafe to DNS TCP port 53 open?

Thank you.

Ports aren't really opened or closed - they just exist. There are no rules in place on a default droplet.

  • For example, if I install a panel (ispconfig, vestacp ..) and have my own DNS, I need to configure iptables port 53 TCP to accept?

You do not HAVE to if you don't want to. There are no rules in place on a default droplet.
