You could achieve this by executing a single command such as, for example:
iptables -I INPUT -i eth0 -m iprange ! --src-range 18.104.22.168-22.214.171.124 -j DROP
After executing that command, any packets which hit the eth0
interface and don't have a source address between 126.96.36.199 and 188.8.131.52 will be filtered.
