    This means there's just one answer, so people can't see what other web sites are hosted on your server. :)

    I think they have a huge database of web sites alongside with their IP addresses, and if you look up an IP, they also display all web sites on that IP.

    can be a good solution block totaly the domain domaintools.com to prevent ip caching, within
    hosts.deny file?

    very thanks.
