Problems with IPv6 DNS :-(

[Sharmila]

Hello Experts,

                I have problems configuring DNS server for IPv6. I am using redhat Linux (kernel version 2.4.18-14.) and am enabling IPv6 by 'insmod'ing  ipv6.o. I got bind 9.3.1 from www.isc.org .  untarred and compiled .I did ./configure -enable-ipv6 and make and make install.
There were no compilation errors and 'named' also starts successfully. I think I am doing some mistake in the zone files.I am trying the following simple setup in my private network:
host1-------------- ---------------HUB ------------------------ host2
(fec0:1234:5678:1234::1/64)  |                  (fec0:1234:5678:1234::3/64)
                                |       
                           DNS server(fec0:1234:5678:1234::2/64)

(host1 host2 and DNS server all connected to the same HUB)

I want to have host1 and host2 in example.domain and would like DNS server to resolve the domain name when looked up from host1.
on host1:
vi /etc/resolv.conf
nameserver    fec0:1234:5678:1234::2

named.conf on DNS server:

options {
        directory "/var/named";
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
        listen-on-v6 { any;};
        // query-source address * port 53;
};

//
// a caching only nameserver config
//
controls {
        inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
        type hint;
        file "named.ca";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
};
zone "::.ip6.arpa" IN {
        type master;
        file "::.ip6.arpa.zone";
};
zone "example.domain" IN {
        type master;
        file "example.domain.zone";
};

include "/etc/rndc.key";
I creaetd the files ::.ip6.arpa.zone  and example.domain.zone
Is it right to create such file???
::.ip6.arpa.zone file on DNS server: ( Thought it's similar to 0.0.127.in-addr.arpa.zone)
 
$TTL 86400
@       IN      SOA     localhost.      root.localhost (
                        1 ; serial
                        28800 ; refresh
                        7200 ; retry
                        604800 ; expire 
                        86400 ; ttk
                        )


@       IN      NS      localhost.

1       IN      PTR     localhost.

example.domain.zone on DNS server:

$TTL 86400
@       IN      SOA     example.domain root.localhost (
                        3 ; serial
                        28800 ; refresh
                        7200 ; retry
                        604800 ; expire 
                        86400 ; ttl
                        )


@       IN      NS      example 

$ORIGIN example.domain
@       3600    IN      A6        64    fec0:1234:5678:1234::2
host1   3600    IN      A6      64      fec0:1234:5678:1234::1
host2   3600    IN      A6      64      fec0:1234:5678:1234::3

Now on host1 ,I do
dig 0.0.0.0 host2.example.domain a6
or
dig :: host2.example.domain a6

It does not succeed.It says,
no servers could be reached;connection timed out;

On server side, in /var/log/messages it says unexpected end of file in example.domain.zone

Can someone please tell me where I am wrong . I am completely new to this.So,I could have made some silly mistakes.So,please correct me and guide me or point me to proper help docs on this.
Also is it compulsory to have DNSSEC enabled for IPv6 DNS ??

Thanks in advance,
