thank you, that is a great part of what I needed to know. So I need my own DNS Server. Fine with me.
But I still don't know exactly what to do.
You say I need to add two subdomains as nameserver entries. That means: at first I only have the IP of my root server. If I need nameservers, I first need to register a domain name on my ip, lets say www.myserver.com
That is where I encounter first problems: when I register my domain name I need to give Nameservers. Do I have to put in my nameserver here alredy? My nameserver subdomain does not exist at that moment, right?!
Even worse: before I can register my domain name, i need to configure a nameserver entry. I don't understand that at all.
I need to give my domain name here, then I can choose between:
- Primary and Secondary Nameserver entry and 3rd Nameserver entry with standard-Zonefile. (you can give the IP of the 3rd Nameserver)
- only secondary Nameserver entry (you can give the IP of the primary DNS)
- primary and secondary nameserver entry and 3rd nameserver entry with own zonefile (you can enter your zonefile here)
So I guess I would take the second choice, give one DNS server of my ISP and my own? I'm really lost!
