   I’ve seen this tool in the past and I’m not sure it’s all that accurate. From what I can tell it looks at the IP address for the web site and then who that IP address is assigned to. These addresses can be “assigned” to a host via direct allocation or they can be SWIP’ed (http://en.wikipedia.org/wiki/Swip) from an upstream provider. Not every provider is willing to SWIP the IP’s so it may come back with a somewhat “false” answer.

   Frank, yeah I noticed that it will return a wrong hosting for some websites. But it worked 90% of the cases when I was playing with it. Good enough I guess .

   It was right for some of my own sites and wrong for others. Interesting tool, though.

   Nice tool Daniel. I just wanted to check its efficiency. So I entered my blogspot blog address and it correctly said GOOGLE.

   This tool is telling us who owns the ip address, not necessarily who they are buying their hosting from directly. I checked 3 websites and 2 were incorrect. The one that was correct was when I tried google.com and of course .. they own their own ip addresses and probably don’t rent them from another provider.

   Here’s a link to another IP tracker:

   Hi Daniel,
   I was very late in coming to know about the project 3. Anyway I managed to write mine. Here is mine post.

    Thanks. it’s interesting tool. but I wonder how this tool gonna work for domain which has privacy enabled.

11. Frank on July 8, 2007 9:02 pm

    Privacy protection should not make any difference in this case. What the tool (appears) to be doing is looking at the IP address for the site. Once you have the IP address you can look up the IP address and that “may” show you who is hosting the site.

    Hello, thanks for the link, I’m one of the two guys behind this little project.

    Just to clarify a couple of points.

    It’s not, to my knowledge, possible to determine the web hosting provider for any website by just taking this data from a database. This is the first thing that most people think we’re doing: we’re not. I haven’t seen many tools that can do this accurately, and those that do simply pull the results from some huge database (which is sometimes obsolete) or/and they don’t support specific country TLDs. And none of them present the results in such a simple way as our tool (:

    Our tool takes various chunks of info from several databases and then tries to do simple “research” and find the web hosting provider. It’s not 100% accurate, and in some cases it’ll be completely wrong (sometimes none of the databases return meaningful info), but we’ve found that it works well enough, and certainly better than doing this research by hand.

    Anyway, thanks again for your attention; have in mind that we are constantly updating the service to make it better and more accurate.

    I think one improvement would be to decipher between the data center and the actual host they purchased hosting from.

    There’s a similar tool which is able to perform an universal WHOIS query for a given domain.
    Here’s the url: http://www.whoistheowner.net
