Nameservers on own domain

[mares992]

Hello,

I have one server where is my Sentora. I'm a little confused with understanding about nameservers. 

I have few domains and want redirect all domains nameservers to one of them.

For example have domain1.com domain2.com domain3.com and have one maindomain.com

Need to redirect nameservers of domain1.com domain2.com domain3.com to ns1.maindomain.com and ns2.maindomain.com and host it on my Sentora.

How can I register ns1.maindomain.com and ns2.? I need separate DNS server? 

If not understand please tell me to try explain better.

Thank you!
