Hi,
you can find my ip range blocker here.

I tested it in PS 1.1
At the moment I use a modified version which simply looks for the hostname of the visitor.

$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);

if (stristr ($hostname, 'co.uk'))
{
   header("Location: www.somewhere.com");
}

But all the approaches are just for unexperienced visitors and can be bypassed in minutes if they know howto.
