If you want to . * store multiple IP addresses or port numbers and match against the entire collection using a single iptables rule. * dynamically update iptables rules against IP addresses or ports without performance penalty. * express complex IP address and ports based rulesets with a single iptables rule and benefit from the speed of IP sets. . then IP sets may be the proper tool for you.
