How do I configure nameservers?

[MariosX]

Hello,
I just installed VestaCP on my VPS and I'm a newbie, I don't know how to configure and host my websites on my VestaCP

I can log in to my web-panel through my VPS and through my full hostname on port 8083
My VPS provider randomly generates hostnames, the hostname is not existant but I will use it for addressing my problem thoroughly

Let's say my VPS:

Hostname:
snf-870477.vm.okeanos.grnet.gr

IP:
85.85.85.85

If I type https://snf-870477.vm.okeanos.grnet.gr:8083 or https://85.85.85.85:8053 I can login to my VestaCP just fine.



I use Hostinger.com for Domain Registrars and let's say I own myfantasticdomain.com
My Hostinger Domain Settings




1) What settings do I need to change here?

If I enter:

I get:



Let me show you my Vesta CP settings:

If I edit snf-870477:


If I edit myfantasticdomain.com
