Okay:

let's look at some DNS records for the nonexistent domain
"yourdomain.com"

@     IN A 123.123.123.3
manny IN A 123.123.123.1
pop   IN A 123.123.123.1
smtp  IN A 123.123.123.1
moe   IN A 123.123.123.2
ns1   IN A 123.123.123.2
jack  IN A 123.123.123.3
www   IN A 123.123.123.3
@     IN MX smtp

(In this example, each machine runs only one IP#.)

Now the only confusing line here, at least to me, is the first line,
that begins with "@" and ends with "3".

It starts with "@" because the "@" sign is shorthand for the domain
assigned to this file by name in the /etc/named.conf file.

It ends with three, because generally, if people type "yourdomain.com"
into a browser they really want to see the same page as if they'd typed
"www.yourdomain.com", and of course, that's on the system with the IP#
123.123.123.3.

On many other lines, machine names alone, without a "." after them,
indicate that the domain name is appended to the end.  In other words,
"jack" is the same as "jack.yourdomain.com.".
