Hi Filuren,
It can check Malaysia IP:
http://whois.webhosting.info/202.186.13.215

The IP above belongs to Webserver.com.my.

Anyways, the results shoudn't be accurate because it checks only the particular IP. Not to mention a host has several IPs plus there might be only a number of sites hosted on the same IP before the host assign an IP to be the shared IP for another few sites.

Thanks.
