title: How to find out hosting provider from domain name?
body: <p>I am looking for a reliable service that has a good database of the hosting providers vs  domain names. I guess some of the domains that are privately hosted cannot be resolved to a definite hosting provider (maybe just to ISP). </p>
  
  <p>I have used webhosting.info (their power whois and advanced whois) which used to give hosting information(not sure) earlier but not anymore. I looked at domaintools.com but couldnt find anything like that in their tools.</p>
  
  <p>I guess I could do a reverse IP on a domain and go to arin.net and get the org name.
  But looking for a free (or paid service) that can do bulk lookups or any reverse dns tools that you recommend or use. </p>
