The address block lists are aggregated by country. What this means is that if for instance IP address blocks 192.168.0.100/24 and 192.168.0.101/24 are allocated to the same country, we will merge them into a single 192.168.0.100/23. That's why our lists may appear smaller in size when compared to other IP address block lists when in fact they are just highly optimized to not waste memory in your router.
All lists are based on data generously provided by the RIRs: RIPE NCC, ARIN, AFRINIC, APNIC and LAPNIC. Last update: 2019-05-21 04:50
