setting DNS for my linux

[Mardiana]

I have registered a new domain called company.com. I have a linux box with 8
IP addresses that connect to the internet. I provide my own NS server for my
domain. Therefore i setup the file below :
/etc/hosts  ---------------------------
localhost  localhost
202.155.42.113 box.company.com box
202.155.42.118 mail.company.com mail
202.155.42.119 ns.company.com ns
202.155.42.120 ns2.company.com ns2
/etc/resolv.conf ---------------------
search company.com
nameserver 202.155.42.119
nameserver 202.155.42.120
/etc/named.conf ---------------------
options {
        directory "/var/named";
};
zone "." {
        type hint;
        file "named.ca";
};
zone "company.com"{
        type master;
        file "company.com.zone";
};
zone "0.0.127.in-addr.arpa"{
        type master;
        file "named.local";
};
zone "42.155.202.in-addr.arpa"{
        type master;
        file "202.155.42.zone";
};
/var/named/company.com.zone ---------------------
@               IN      SOA     box.company.com. hostmaster.company.com. (
                        1999111502 ; serial
                        8 ; refresh
                        2 ; retry
                        1 ; expire
                        1 ; default_ttl
                        )
@               IN      NS      ns
@               IN      NS      ns2

ns               IN      A       202.155.42.119
ns2             IN      A       202.155.42.120
mail            IN      A       202.155.42.118
www          IN      CNAME   box
ftp              IN      CNAME   box
box            IN      A       209.15.54.113

/var/named/202.155.42.zone ---------------------
@              IN      SOA     box.company.com. admin.company.com. (
                        1999111502 ; serial
                        28800 ; refresh
                        7200 ; retry
                        604800 ; expire
                        86400 ; default_ttl
                        )
@               IN      NS      ns.company.com.
@               IN      NS      ns2.company.com.
118             IN      PTR     mail.company.com.
119             IN      PTR     ns.company.com.
120             IN      PTR     ns2.company.com.
113             IN      PTR     box.company.com.
/var/named/named.local ---------------------
@               IN      SOA     localhost.      root.localhost. (
                        1997022700 ; serial
                        28800 ; refresh
                        14400 ; retry
                        3600000 ; expire
                        86400 ; default_ttl
                        )
@               IN      NS      localhost.
1               IN      PTR     localhost.

All of those configuration just resolve box.company.com, ns.company.com,
ns2.company.com, and mail.company.com.
What should i do if i want anyone can resolve the domain itself
(company.com) beside box.company.com / ns.company.com / etc ? (so i can use
: http://company.com for my web address and @company.com for my email
domain)
Any help would be appreciated!

Thank you,
Mardiana
