Problem with DNS server

In login page http://myip/vhosts/ehcp have this

"Your dns/server ip is set as:MY IP, if it is not detected/set correctly, please set it in your Settings"

In Settings i add this Local ip of server: my ip adress
dnsip (outside/real ip of server): my ip adress

Which part of the ip adress is wrong?

and how i can redirect co.cc domain to my hosting i have domain in my ehcp thank you :)

Starting Nmap 4.76 ( http://nmap.org ) at 2009-09-01 21:15 EEST

Not shown: 990 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
110/tcp open pop3
143/tcp open imap
993/tcp open imaps
995/tcp open pop3s
8080/tcp open http-proxy

this is nmap ports is open :)

if your server has real/static/outside ip, then both ips same
if your server is inside an internal network, has ip like 192.168.1.10, then,
local ip: 192.168.1.10
dnsip: your outside ip

to redirect your domain:
set dns of your domain co.cc to ns1.co.cc, ns2.co.cc, in your registrar (the place that you buy your domain)
you may need in registrar: a register dns feature may exist there, then, register ns1.co.cc with your external ip,

thats it.
