Bind: Can you configure multiple domains using the same nameserver

Can you add multiple domains to a nameserver without creating a new IP address? I have one IP address on my machine and have configured forward and reverse zone files. Names are resolving fine.

I know I can add another domain to the named.conf file and create new forward and reverse files. what name server IP would i add to the forward file for the second domain and how is it configured in the forward file? Also I have named my reverse file with the reverse of the first 3 octets of my system IP address. I need to change that and what should i use for the reverse zone names?

Code:

named.conf:

zone "myserver.com" {
        type master;
        file "fwd.myserver.com.db";
        allow-update { none; };
};

zone "xx.xx.xxx.in-addr.arpa" {
        type master;
        file "xx.xx.xxx.db";
        allow-update { none; };
};

zone "newdomain.com" {
        type master;
        file "fwd.newdomain.com.db";
        allow-update { none; };
};


/var/named:

cat fwd.myserver.com.db

$TTL 86400
@       IN      SOA     nameserver.myserver.com.     root.myserver.com.      (
                                10030   ;Serial
                                3600    ;Refresh
                                1800    ;Retry
                                604800  ;Expiry
                                86400   ;Minimum TTL
)
; Name Server
@       IN      NS      nameserver.myserver.com.
;A Record Definitions
nameserver	IN	A	xxx.xx.xx.xx
server1        IN      A	xxx.xx.xx.xx
server2      IN	A	xxx.xx.xx.xx

How do I configure the forward zone record for the newdomain? i have used the one system IP address for the name server in the myserver.com domain.
