Generate the latest country IP ranges in CIDR notation

## How it works

The shell script `generate.sh` will download the latest RIR statistics files ([RIR statistics exchange format](https://www.apnic.net/about-apnic/corporate-documents/documents/resource-guidelines/rir-statistics-exchange-format/)) from the following five Regional Internet Registries (RIRs).

Source: [IANA Number Resources](https://www.iana.org/numbers)

URLs:

```sh
https://ftp.apnic.net/stats/apnic/delegated-apnic-latest
https://ftp.arin.net/pub/stats/arin/delegated-arin-extended-latest
https://ftp.ripe.net/ripe/stats/delegated-ripencc-latest
https://ftp.afrinic.net/pub/stats/afrinic/delegated-afrinic-latest
https://ftp.lacnic.net/pub/stats/lacnic/delegated-lacnic-latest
```

It then grabs entries from the files above. Generate `country_code.txt`. Convert IP ranges to CIDR notation. Generate IP files for each country.

### Example

Generate Japan IPv4 ranges from [APNIC](https://www.apnic.net) and save them to `JP_IPv4.txt`.

```sh
curl -sL https://ftp.apnic.net/stats/apnic/delegated-apnic-latest | \
grep "apnic|JP|ipv4" | \
awk -F '|' '{ printf("%s/%d\n", $4, 32-log($5)/log(2)) }' | \
tee JP_IPv4.txt
```

## Usage

This will generate all countries and save IP files to your current directory.

```sh
curl -sL https://github.com/HackingGate/Country-IP-Blocks/raw/master/generate.sh | sh
```

The country code is under [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2) standard.
