Drop-in replacement for the network lists previously available at based on Internet number resource usage data published by the Regional Internet Registries (RIR). The data is organized by country code (ISO 3166).

This repository is updated daily (if the underlying data changes).

Update notes

  • 2022-12-18: Fixed prefixes for some delegated networks as reported by RF3, see this thread for details

How to use

To download the delegated IPv4 networks for Switzerland, try:
$ curl

To download the delegated IPv6 networks for Switzerland, try:
$ curl

The data (IPv4 + IPv6 combined) is available in JSON format as well:
$ curl

The resulting JSON will look similar to this:

  "country": "Switzerland",
  "country-code": "CH",
  "delegation-status": [
  "mode": "aggregated",
  "subnets": {
    "ipv4": [
    "ipv6": [

Instead of carpet banning an entire geographic region, it might be more effective to just ban specific internet providers based on their autonomous system number (ASN). Check out the ipverse-asn-ip repository for more information.
