www.xyz.com working, but xyz.com not

[pg001]

I need help on something coz I cant seem to get it right...

when I type www.xyz.com on my browser, my website shows but if I just put xyz.com only I get server not found error.

when I ping www.xyz.com I get a different IP from xyz.com.

pri.xyz.com looks like this:

$TTL 86400
@ IN SOA ns1.abc.com. paul.xyz.com. (
2008070309 ; serial, todays date + todays serial #
28800 ; refresh, seconds
7200 ; retry, seconds
604800 ; expire, seconds
86400 ) ; minimum, seconds
;
NS ns1.abc.com. ; Inet Address of name server 1
NS ns9.zoneedit.com. ; Inet Address of name server 2
;

MX 10 mail.xyz.com.

xyz.com. A 122.12.203.204
www A 122.12.203.204
mail A 122.12.203.204

xyz.com. TXT "v=spf1 a mx ptr ~all"

The dns record is correct. But are you really sure that your dns server is authoritive for the domain and not e.g. the dns server of your domain registry?

how do I make sure that my dns server is authoritative for the domain and not the dns server of my domain registry?

what I did on my domain registry was to put just

ns1.abc.com as the primary name server
and left secondary name server blank

ns1.abs.com was done following this HowTo:

Do you see the right nameservers listed in the output of
dig ns yourdomain.com?
