Package ipset

Manage Linux IP sets


IP sets are a framework inside the Linux kernel since version 2.4.x, which can
be administered by the ipset utility. Depending on the type, currently an IP
set may store IP addresses, (TCP/UDP) port numbers or IP addresses with MAC
addresses in a way, which ensures lightning speed when matching an entry
against a set.

If you want to:
 - store multiple IP addresses or port numbers and match against the collection
   by iptables at one swoop;
 - dynamically update iptables rules against IP addresses or ports without
   performance penalty;
 - express complex IP address and ports based rulesets with one single iptables
   rule and benefit from the speed of IP sets
then ipset may be the proper tool for you.

Version: 7.21
