    :Given a website URL, what's the best way to find out all the information

    :- where the site is hosted, either internally by the company or by a hosting
    :company, webfarm, etc,

    nslookup or dig to find the IP address(es) associated with the URL.

    telnet to port 80 of the IP, issue a GET request with a Host: header
    and manually examine the top of the output to determine whether there
    is redirect header or HTML meta redirect header sending you to another
    site. If so, loop back the process applying to that site.

    When you have found the site that gives meaningful content for the URL,
    then look at the IP address and see if you recognize it as being
    part of your company. If not, use whois or equivilent tool to find out
    who that IP block belongs to.

    If you are *sure* that the IP belongs to your company, or if you
    are sure that your company is renting dedicated server space (no-one
    else's web site on the same machine), then you can use nmap to probe
    to find out more about the machine... if it isn't sufficiently firewalled
    to prevent that.

    You can examine the headers returned when you telnet'd to the appropriate
    location, as they will often indicate which server software and possibly
    even what kind of platform.

    If the IP block doesn't belong to you or might be shared, look at
    the Technical Contact information returned by whois and write a message
    to that contact.

    Write a message to webmaster at your site.

    If you track down a hosting company but can't figure out who the
    official contact is within your organization, contact the hosting
    company and ask what to do. They might tell you to send a letter on
    company letterhead... but at least then you'd know the procedure.
