IPCC — Aggregated Country CIDR Generator

IPCC is a program for generating aggregated CIDR blocks by country based on official data from Regional Internet Registries (RIRs).

It supports IPv4 and IPv6 and can automatically merge adjacent networks.

Overview

• Generates CIDR blocks by country (ISO 3166-1 alpha-2)

• Supports IPv4 and IPv6

• Automatically collapses adjacent networks (collapse)

• Uses RIR data:

  • RIPE NCC
  • ARIN
  • APNIC
  • LACNIC
  • AFRINIC

Usage

Generate USA IPv4:

./ipcc --country US --output ~/us.zone

The program will download RIR data, select networks of the specified country, merge adjacent CIDRs, and save the result to a file.

Testing

To run tests, use pytest:

pytest

Все тесты проходят, что гарантирует корректность парсинга и объединения сетей.
