Banning entire isp

I am using apf firewall based on iptables. I need to temporarily ban an isp, the example given in the firewall config is : (blocking 24.202.11.* I think)

but I need to ban 24.202.*.*

Does anyone have a rule to do this?

BTW this particular ip is just an example from the documentation.

Have you considered using / do you have the facility to us... htaccess for this? (Are you running on an apache web server [webmasterworld.com]?)

Thanks I will try that, I am running apache but I think it's best just to ban from the entire server

I should add that a good place to learn about why you're now using /16 instead of /24 would be to learn about Subnetting [en.wikipedia.org]. It will save you some grief later, expecially if you're messing with firewall rules. :)

Please note that some ISPs have a tendecy to sue once you ban them.

Can you point us to a concrete example of that?

I've been in the Internet industry for quite a while and have never heard of an ISP suing anyone because they were blocked by their firewall rules unless there was some sort of pre-existing contractual relationship where they had agreed to pass traffic for them.

Obviously they wouldn't have a legal leg to stand on, somehow trying to force someone into allowing their packets on the other persons server or network.
