GeoipWhoisAsnCountry

Uses the node package "@ip-location-db/geo-whois-asn-country" to build a ruby structure for efficient lookup of IP -> country both for IPv4 and IPv6.

Installation

Install the gem and add to the application's Gemfile by executing:

bundle add geoip_whois_asn_country
yarn add @ip-location-db/geo-whois-asn-country

Usage

require 'geoip_whois_asn_country'

# First run will take a couple of seconds and build the ruby strucutre
# and cache it into tmp/cache/geoip-country-cache
country_code = GeoIpCountry.lookup('1.2.3.4')
=> :CN

country_code = GeoIpCountry.lookup('2001:db8::')
=> :FI


GeoipWhoisAsnCountry.configure do |config|
  config.cache_path = "tmp/cache/geoip-country-cache"
  config.ipv4_num_csv_path = "./node_modules/@ip-location-db/geo-whois-asn-country/geo-whois-asn-country-ipv4-num.csv"
  config.ipv6_num_csv_path = "./node_modules/@ip-location-db/geo-whois-asn-country/geo-whois-asn-country-ipv6-num.csv"
end
