I started paying for a VPS-server at Contabo.com recently. I've read quite a few guides about setting up a VPS-server properly, - but I can't find any 'best practice' regarding the hostname.
At the moment, it's quite the horrible hostname (along the lines of: vmi123456.contaboserver.net
). I can understand that I simply can change it, by changing it in /etc/hostname
(it's a Ubuntu 16.04 server). But somewhere I read that some hosting-companies reset the hostname upon rebooting.
But no one addresses my issue... Should I do it? Because what if someone else has a server with Contabo, and both he and I rename the server to foo.contaboserver.net
? What will then happen - which consequences will that cause? And is it cool to do it, as long as I choose something that has a high chance of being unique? And can I check if a given hostname is available or not?
Or an even better question is, - what if someone else renames their VPS to have the same name as mine currently have (vmi123456.contaboserver.net
) - will that cause me problems?
