How to block a group of IP's with linux firewall

I am using Redhat 9 and need to block a whole group of IP's using
IPTABLES. I tried 64.84.0.0 but that didnt do it. How do I block the
who range?

Look at the manual, I think this would do it...

iptables -t filter -I INPUT -p tcp --source-addr 64.84.0.0/16 -j DROP
iptables -t filter -I FORWARD -p tcp --source-addr 64.84.0.0/16 -j DROP

Do a google search for blocking domains also...I ran across the answer
in that search once.
