Regarding the IP Food Script website that Sasha pointed out yesterday, I
was digging into my library here, and I came across a script that I
wrote with the help of a guy on the Experts-Exchange, as follows:
#!/usr/bin/perl
print "Location: ";
# Look for their hostname or IP address. Each if-else query checks the
browser to see if it
# is originating from the site of one of our competitors. You can create
a new entry simply by
# adding a new if-else sequence with the new competitors domain name and
dns address.
if (($ENV{"REMOTE_HOST} eq "www.asaint.com") || ($ENV{REMOTE_ADDR"} eq
"199.103.162.253"))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "asaint.com") || ($ENV{REMOTE_ADDR"} eq
"208.206.42.254"))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.pagedigital.com") || ($ENV{REMOTE_ADDR"}
eq "38.253.192.61"))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.avexxix.com") || ($ENV{REMOTE_ADDR"} eq
" "))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.sigma-micro.com") || ($ENV{REMOTE_ADDR"}
eq "204.95.237.194"))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.dydacom.com") || ($ENV{REMOTE_ADDR"} eq
" "))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.colinear.com") || ($ENV{REMOTE_ADDR"} eq
"209.86.106.186"))
{print "http://www.datamann.com/sorry.html\n\n";
}
else{
if (($ENV{"REMOTE_HOST} eq "www.resoft.com") || ($ENV{REMOTE_ADDR"} eq
"204.50.196.23"))
{print "http://www.datamann.com/sorry.html\n\n";
}

}
else{
# if the browser does not meet the above criteria, they then are let in
as follows
print "http://www.datamann.com/welcome.html\n\n";
}
This obviously was designed to prevent our competitors from seeing our
website.... The same commands are probably used in that IP Food Script
that we discussed the other night, as a means of providing the search
engines the desired optimized page....
So essentially, to beat the IP Food Script, a bot has to deploy to
another host server that is not on the Food Script hit list, then query
the page to be indexed. If you are a competitor, just spoof the host IP
of a search engine spider on your own server, then query the 'optimized
HTML page'.
