ipset - combine individual IP and network subset [SOLVED]

Hi to all,
I am trying to figure out how to create a ipset set that will combine an individual IP & a network subnet.

From man pages it should be:
create blacklist4 hash:ip family inet hashsize 4096 maxelem 65536

add blacklist4
add blacklist4

    @gromovnik use hash:net instead of hash:ip:

    ipset create blacklist4 hash:net hashsize 4096 maxelem 65536
    ipset add blacklist4
    ipset add blacklist4

    Remember, each IP is also a network, an IPv4 single host is a /32, an IPv6 single host is a /128.

    Also keep in mind that if you are doing small networks hash:ip may be quicker as hash net on ipv4 requires the looking up 32 hashes, 128 for ipv6.
