Banning ALL IP addresses from Africa

[ocsmike]

I posted this on merchant colutions and see now it is more appropriate here...

I am really getting hammered by African fraud. I've stopped all international orders but they just fill in US addresses to test out their stolen credit cards.

I check the IP addresses and ban them as they come in and have tried to do ranges but I must be missing the ones they use because they just keep coming in...

But can someone give me the range of IP addresses, in the correct form, to ban ALL orders from ANYWHERE in Africa.

These scammers are driving me nuts with dozens of fraud orders a day.

That's never a good thing. Best advice I can give off the top of my head on this one is to try DNSstuff: On-demand DNS and network tools to analyze, diagnose and monitor a domain or IP address. On the left side of the page there is a search box for IP Information. Throw in one of the IP's that you have and it should give you an IP range for that country.

Thanks... my fraudster is from Ghana....Following your suggestion, I learned I that this is the range I want to block.

41.210.0.0 to 41.210.63.255

I can't seem to find the correct way to enter this on the IP block form on Yahoo.... any suggestions?

I believe the syntax you will need to use is 41.210.63.255/18. This will block 41.210.0.0 through 41.210.63.255 for a total of 16384 IPs.

Yahoo uses CIDR for range blocking. I used this site to get the proper syntax: IP Address Guide | Ping | Traceroute | DNS Lookup | CIDR | Geolocation | HTML Validator. DNS Stuff is sometimes more accurate and easier to use then Yahoo's reverse DNS which is why I recommended them.

Thanks, Jeff....
I punched it in and hope it stops .... this guy has been hitting me hard for weeks now. Hopefully he'll move on.
Have a great weekend!

Hi Mike,

I'm from South Africa. We've been very sensitised to against fraud and find that Nigeria and Ghana are countries where fraudsters have taken refuge.

Sorry that you were hit by an African. It is a poor reflection on the good progress that is being made here.

Regards,

Adrian

I am getting at least a few hundred every month from Gambia.
212.60.73.125
Country EU # country is really somewhere in African Region

Do you know what range I would block for them, Yahoo has been no help, I have to keep adding and deleting IP's because I am over 100.

When I try to report them to credit card companies, I keep getting passed around, no one seems to care. I guess they dont worry because if a charge goes through it falls back on the merchant.
