For net types the networks are not exploded, of course: # ipset create test hash:net,port # ipset add test 192.168.0.0/30,tcp:80-82 # ipset list test Name: test Type: hash:net,port Header: family inet hashsize 1024 maxelem 65536 Size in memory: 16856 References: 0 Members: 192.168.0.0/30,tcp:80 192.168.0.0/30,tcp:82 192.168.0.0/30,tcp:81 However please note, the "net" types slow down linearly with the number of different network prefixes in the set.
