You could achieve this by executing a single command such as, for example:
iptables -I INPUT -i eth0 -m iprange ! --src-range 220.127.116.11-18.104.22.168 -j DROP
After executing that command, any packets which hit the eth0
interface and don't have a source address between 22.214.171.124 and 126.96.36.199 will be filtered.
