ipset is a companion application for the iptables Linux firewall. It allows you to setup rules to quickly and easily block a set of IP addresses, among other things.

Installation

Install ipset from the Official Repositories.

Configuration

Blocking a list of addresses

Start by creating a new "set" of network addresses. This creates a new "hash" set of "net" network addresses named "myset".

# ipset create myset hash:net

Add any IP address that you'd like to block to the set.

# ipset add myset 14.144.0.0/12
# ipset add myset 27.8.0.0/13
# ipset add myset 58.16.0.0/15

Finally, configure iptables to block any address in that set. This command will add a rule to the "INPUT" chain to "-m" match the set named "myset" from ipset (--match-set) when it's a "src" packet and "DROP", or block, it.

# iptables -I INPUT -m set --match-set myset src -j DROP

Other Commands

To view the sets:

# ipset list

To delete a set named "myset":

# ipset destroy myset

To delete all sets:

# ipset destroy

Please see the man page for ipset for further information.
