i'd like to know how no-ip get my address

[midnite]

i am working with http://www.dyndns.com, yet his page http://checkip.dyndns.org got my ip address wrongly!! (why will it happen?) i have installed the one stated here : https://www.dyndns.com/support/kb/archives/...s_services.html, yet i have some problem in getting the ip address through my router as my router gives the ip address in this way

			<tr>				<td width=50%>Public IP Address</td>				<td align=center><script>					document.write(va_PublicIpAddress);									</script></td>			</tr>

yet i have that alright when i was using no-ip, yet its free plan doesn't support wildcard.. so.. if i can get and update the ip in dyndns as no-ip did, that will be GREAT!!thanks for helping in advance

i'd like to give more information about it.this is what noip2 debug information:

> GET http://dynupdate.no-ip.com/ip.php HTTP/1.0> User-Agent: Linux-DUC/2.1.1>< HTTP/1.1 200 OK< Date: Fri, 05 Jan 2007 00:00:14 GMT< Server: Apache/1.3.27 (Unix) PHP/4.3.2< Connection: close< Content-Type: text/html<< 218.252.52.158! Our NAT IP address is 218.252.52.158

but i got 222.166.160.xxx by my browser at http://dynupdate.no-ip.com/ip.php*xxx because it keeps changing nearly every time i hit it.the 218 one is the right one and i don't know what's going with the 222 one..any one have some clue ??
