newbie question

[Daniel Kirk]

hi there,

I've spent over a day reading materials on Bind and it seems simple enough
but there are a couple of points which are really really confusing me.

I have my own server with 1 ip address hosted by an ISP.  I want my server
to be the Primary & Secondary DNS servers for my domain.

I am (quietly confident that I'm) running named.

If I were to change my name servers with internic, I should specify my
Primary DNS server having the IP of my machine (right?).  But what do I use
as the name of the machine?

Say my machine is called a.b.net (where b.net is the name of my ISP), and I
want to host the domain www.mydomain.com.  I want my Primary dns server to
be dns0.mydomain.com and my secondary server to be dns1.mydomain.com, and
for www.mydomain.com to use these dns servers.  Is that possible, or do I
need to have mydomain.com using different name servers before I can setup
dns0 & dns1.mydomain.com?

If my machine is called a.b.net (Where b.net is the name of my ISP), how do
I go about naming my name server that is apparently running?

Hope these questions make sense, I think I'm not too far away but am just
confused by a few simple things

thanks

Dan
