I just need to look up few ip addresses and find out what domains hosted on it.I tried to buy a silver membership,but it's always failed.If Anyone can help me,I will pay you $5 by paypal.
Thanks...

Sorry,I forgot to notice,it's whois.sc service.

See what you can find with http://whois.webhosting.info

I know that,but's it's not accurate

both services show only gTLD domains not ccTLD or subdomains because they process zonefiles

so neither is accurate
