As per info in http://lists.netfilter.org/pipermail/netfilter/2005-September/062859.html, ipset of iphash of 20Million IPs, takes around only 80MB. I understand that this might be simply multiplication of 20Million with 4 bytes which IP takes if stored normally. But when I try to replicate this I am getting size in memory as 506,481,176 (around 483MB) for number of entries 16,581,375. This comes to around 30Bytes per IP. I have got this values from ipset -L command Is this much size anticipated? -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
