I was under the impression from the original post that the OP wanted to whitelist one or a small number of IPs, not blacklist a limited number or range of IP addresses.
In either case, this could also be handled at the web server level such as limiting access to a directory via a .htaccess entry (if Apache), though I'd have to do a little Googling to come up with the syntax for that.
Make it so only specified IP address can see site
In PHP, how can I make it so only a specified IP address can see a website? All other users will be directed to another website?

<?php
$allowedIps = array(
'1.2.3.4',
'1.2.4.6'
);
if(!in_array($allowedIps, $_SERVER['REMOTE_ADDR']))
{
header('Location: http://some.other.site/');
exit;
}

@NogDogNov 21.2009 — #OP: Please be informed - if the visitor comes through a proxy or firewall on their end their WAN IP might be the same as anyone else on their LAN. So you might intend to block one user but might end up blocking many sharing that IP. Plus if your filter allows wildcards to ban ranges, one typo and you could ban an entire class C, B or huge block of unintended addresses with one unnoticed typo. And even proxy servers can be used to bypass an IP ban anyway unless you implement an anti-blockingscript . In short, there are a few notable potential headaches if this kind of policy is not applied sensibly and carefully.
