I need to assign a Fully Qualified Domain Name to my Ubuntu VPS, but before I do it I would like to understand what it means. Is this...
$ hostname --fqdn
$ hostname: Name or service not known
normal ie meaning that there is no FQDN yet assigned? Also I think any domain like www.example.com
is a FQDN so assigning a FQDN to my VPS does not just mean hosting a domain (which I am doing already) right? My VPS already has an IP address and hosts domains so can anyone please tell me what assigning a FQDN to my VPS means?
