I setup nameservers and hostname for server now I think with success. Domain is pointed by nameservers and hostname to the server. Nameservers are named by that domain.

How long it can take that all the things appear on internet.

What could be the problem if this doesn't work.

I saw some thing in CPanel/WHM that I think might be wrong.
In section Edit DNS Zone when I click to edit 'ns02.mydomain.biz' in two lines there is 'NS01.mydomain.biz ' Is this OK or not. It is the setup for NS02 but there in upper line is NS01 and this is ZONE FILE for ns02.mydomain.biz

I created account for that domain and every now and then I point my browser to the mydomain.biz to see if it is active but nothing. When I input IP I include for this domain, there is some respond from browser but not by domain name.

Thanks

It takes roughly 24 hours for nameserver records to update over the internet in average circumstances.

It certainly isn't right for the record to be NS01.mydomain.biz, you need to edit that to point at your domain.

The problem is in DNS ZONE File for NS02.mydomain.biz

In the first line it is NS01.mydomain.biz I need confirmation that this is surely not OK, and then I will change it to NS02.mydomain.biz

It take around 12 hours to relect the changes. Each registrar update DNS changes twice a day.
Max is 24 hours
:D
