nameservers on different servers

[Vpower]

I have 2 servers named sharky.mydomain.no and sharky01.mydomain.no.
I only have nameservers setup on sharky01 as ns1.mydomain.com and ns2.mydomain.com.
Now, I have domain mydomain.net and I want to setup new nameservers:
ns1/ns2/ns3/ns4.mydomain.net.

ns1 and ns3 should be on sharky01 and ns2 and ns4 on sharky.

How do I do this? Is this the correct approach?
