Finding a company by their IP address?

Posted on 2005-04-20
Last Modified: 2010-04-10
I am trying to find out companies that are visiting our company web site.  We have access to logs through CNstats, and it basically gives us the IP address and host name of visitors.  Is there a way to find the company that is viewing our web site?  So far we have just been looking up the hostname and trying to decipher that, and occasionally running a tracert on the IP to see if we can find anything that way.

    Hi bdietz,
    The closest thing you'll be able to do is an IP WHOIS.

    You can do this at

    This may give you the precise details, but will often just list the details of the ISP.

    Reverse DNS (as you're doing) is probably as good a method as any though!

    Does that help?
