ipset binary package in Ubuntu Bionic armhf

 IP sets are a framework inside the Linux 2.4.x and 2.6.x kernel which can be
 administered by the ipset(8) 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
    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.
