Goodmorning to everybody,
I would like to change the hostname of my root server with 'ubuntu-18.04' instead of 'v3303002220685104720' .
Since I purchased a domain (say fireworks.com), my fqdn would be ubuntu-18.04.fireworks.com
Am I also required to change accordingly the rDNS of the IPv4 in the Network section of the Server Control Panel?
