Please verify if the steps I'm doing is right or wrong:
I just got a dedicated server with a block of ips.
I'm going thru the initial setup for this server.
1. The server has IP: xx.xx.xxx.190
2. I change the Hostname from some initial value to myowndomain.com (which I have registered and point to some temp. DNS)
3. I want to setup the Primary Nameserver & Secondary Nameserver so I went to the registrar and setup NS for myowndomain.com using 2 out of the block IPs allowed.
NS1.myowndmain.com -> xx.xx.xxx.191
NS2.myowndmain.com -> xx.xx.xxx.192
Questions: In step 2 I said myowndamain.com is point to same temp. DNS. Can I now change the DNS of myowndomain.com to point to the to NS servers I just created in step 3? Any problem here?
4. In the WHM I enter value as following:
Primary Nameserver: NS1.myowndomain.com and click assign ip address; it then says ip xx.xx.xxx.190 has been assign

Why it use the main ip of my server? Is this correct? Should I then need to change to this ip in the registrar?
Secondary Nameserver: NS2.myowndomain.com then click assign ip address; it then says no more ip available to assign

How come? I have a block of 10 and have not used any?
Please help!!!
