Iptables uses different kernel modules and different protocols so that user can take the best out of it. As for example, iptables is used for IPv4 (IP version 4/32 bit) and ip6tables for IPv6 (IP version 6/64 bit) for both tcp and udp. Normally, iptables rules are configured by System Administrator or System Analyst or IT Manager.
