How to block several IPs in one command using iptables?

Hi all

I want to block several IP addresses using iptables but I don't want to block every IP in a separate command. These IP addresses are not in same subnet.Is there any way to add more than one IP in only one command without using any other program or plugin?

Code:

for IP in 192.168.0.10 192.168.0.100 10.200.1.200 69.56.15.20; do /sbin/iptables -A INPUT -p ALL -s $IP -j DROP; done

That's how I'd do it. Never tried to put multiple sources as IP's in one command, don't think it would take such option, only ranges in same segment or range, etc. I'd rather them be separate anyways to be honest.
