Hello Guys

I bought new vps server and it come with one IP
I'm having problem in setting proper DNS server as I only have one IP so I can only make ns1.mysite.com

but I can't make ns2.mysite.com

so my question how can I use everydns.com service to solve this dns issue, I want to have correct DNS so all visitors can access my site without dns problem

I appreciate your help ?
