Country-IP-Blocks

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) from the following five Regional Internet Registries (RIRs).

URLs:

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 and save them to JP_IPv4.txt.

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.

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

The country code is under ISO 3166-2 standard.
