    Any server-side language can detect the IP address of a request (though it can be spoofed), so you'd just need to redirect (or just return a blank page) when an IP address on your blacklist is found.

    You have domain names? Ping them to get IP address.

    If you're trying to block everyone who uses those ISPs to access the internet, you'll need to determine the IP address ranges they each use.

    no, there's gotta be a way to run their ip and see what ISP they have, then block it if it is a certain ISP.
