help changing ns1 and mail prefix

[royald]

Hi everyone I'm new and kind of need a bit of help working something out.

I want the ability to change things like mail.mydomain.com to something like mail2.mydomain.com. To change the mail server

I also want to display in my WHOIS results NS1.mydomain.com and so on...

is this done through the domain registrar or the hosting company?

its quite obvious I don't know much about this, can anyone help? please?

You can use the DNS service of your registrar for this. First you need to declare hosts like mail ns1 etc and set the IP addresses for these hosts. Then you can use them for your hosting.
You could also do that at the webhost level or even use a third party DNS service.
It all depends where you decide to host the DNS for the domain.
