DNS Records

I have not understood how do we change DNS records.

I want to create some NS and A records. For example I want to create:


ns1.mydomain.tld A myip
ns2.mydomain.tld A myip
mydomain.tld NS ns1.mydomain.tld
mydomain.tld NS ns2.mydomain.tld
server.mydomain.tld A myip

What should I write in my DNS zone file? If I wrote those, will it work? Is there any manual, which explains how do we create DNS records? Will CWP releasy any graphical DNS zone manager, where the user would be able to add easily records, change or delete and don't have to edit file with strange records, numbers etc? For example I can see a record showing something IN A number something Can you help me, in creating those records?
