I have 3 small VPS instances in the web, and I want to improve the routing between them. These servers are used for some private things and one of them is for hosting websites. My problem is that the service provider does not provide a proper interface to manage DNS entries, which means, that my domain name points to only one server. I can't say that I want sub.doma.in point to one of my other servers, only that the domain points to that single VPS where my website is hosted.
Can I setup a DNS server on the VPS where the DNS of the provider is pointing my domain too? Is that possible?
