You could achieve this by executing a single command such as, for example:
iptables -I INPUT -i eth0 -m iprange ! --src-range 184.108.40.206-220.127.116.11 -j DROP
After executing that command, any packets which hit the eth0
interface and don't have a source address between 18.104.22.168 and 22.214.171.124 will be filtered.
