sub-domain : use 2 own ips or 1 own ip and ns2 of my hoster?

[Puma]

hello,

sorry for my bad english.

Is that to create a subdomain from my main domain name for my clients, I must have 2 own ip on my machine, or can I have one ip and use the secondary dns for my dedicated server provider please?

Thanks you
Regards.
Alex

I'm not sure what you're asking.

What DNS servers (names and IP#s) do your main domain name use? Why can't you use the same domain names?
