I have some questions which I am sure I am overthinking and not quite understanding yet.

First:
i.p. addresses and adding i.p.s using WHM
My server has 1 i.p. address as per norm, when I use the add i.p. function is this adding more public i.p. addresses available to me or is that i.p. addresses based on the local server network? Also, what i.p. ranges can I use, what is a sensible range. My first instinct is to use the typical local addresses such as 192.168.0.1-25

Secondly:
Nameservers
I understand the concept of DNS and what they do. Do you need to use your own name servers and is it as simple as it is suggesting. input ns1.domain.com and ns2.domain.com then update the nameservers with my domain registrar? Do these two name servers for the system need separate public I.P. addresses, can they use the same i.p. address as the main server or can these be the local i.p. addresses that you can add?
For customers with domains do they need to point their domain to the same nameservers and i.p. address of the server or is it the local i.p. address of their account?

So joe blogg has an account on 192.168.0.1, do they need to direct their registrar to my name servers and their own i.p. or the server's public i.p.


Thanks in advance for help, I am sure it's way simpler than I am thinking and obvious to most but half way through an IT degree has added all these questions regarding public and local i.p. addresses and what WHM is actually doing when you add one.

If your server has only one IP assigned to it and you want to use custom nameservers which are hosted locally you would need to use the same public IP address for both of them.

Thank you for your reply, you didn't answer my question regarding i.p. addresses, when adding ips is that a function creating ip addresses on the local network or public ip address used to assign to the server
