/etc/hostname and /etc/hosts

When I set up a droplet I was “lazy” with naming. Now my hostname is “”. And there are two websites on the server (NGINX).

I want to change hostname from “” to Production. But I am slightly lost since two FQDN are pointing to the same machine.

Should I do as following:

change in /etc/hostname to Production (as from now it was (* this one for me is logical *)

change in /etc/hosts: SITEA.COM SITEB.COM (now it was

I am especially lost by this loop-back.

Or should I do: (real-ip) SITEA.COM (real-ip) SITEB.COM

Or should I just Production

If u said your server in nginx web server. Its better you set your domain to DO nameserver and pointing domain to A - “ip address” and setup your nginx config with different domain.
