Will I need to install/configure DNS?

Hi,

I have never used unmanaged VPS before so need to ask one question.

If I want to host a website for e.g. www.somesite.com on my server, then from where will I get primary and secondary nameservers?

Because normally in shared hosting we have CPanel where we add the domain in control panel and then it provides us with primary and secondary DNS (given by hosting provider) which we have to set in our domain control panel (from where we bought domain)

Is this how it works in VPS too? I understand there would be no CPanel unless I buy one and I will have SSH access but will I just add/configure domain using SSH and not have to worry about setting up any nameservers which will be provided by DigitalOcean right!?

Thanks
