A VERY quick and dirty ruby script to pull ASN ranges from a query.

asn.rb

#!/usr/bin/env ruby

require 'json'
require 'mechanize'
require 'nokogiri'

@agent = Mechanize.new
country = "us"


def countries()
  countries = []
  html = @agent.get("https://ipinfo.io/countries/").body()
  Nokogiri::HTML(html).css("tr").each do |tr|
    td = tr.css("td")
    if td.length > 0
      name = td[0].text
      url = td[0].css("a")[0]["href"].split("/")[2]
      counts = td[1].text
      country = {"name"=>name, "cc"=>url, "counts"=>counts}
      countries.push(country)
    end
  end
  return countries
end

def asn(country_code)
  asns = []
  html = @agent.get("https://ipinfo.io/countries/#{country_code}").body()
  Nokogiri::HTML(html).css(".main-content").css("table").css("tr").each do |tr|
      td = tr.css('td')
      if td[0] != "" 
        if td != nil and td.length > 0
          asn = td[0].css("a")[0]["href"].split("/")[1]
          name = td[1].text
          count = td[2].text

          asn = {"name"=>name, "asn"=>asn, "count"=>count}
          asns.push(asn)
        end
      end
  end 
  return asns
end

def ranges_from_asn(asn)
  ranges = []
  html = @agent.get("https://ipinfo.io/#{asn}").body
  Nokogiri::HTML(html).css("#blocks").css("table").css("tbody").css("tr").each do |tr|
    td = tr.css("td")
    range = td.css("a").text.gsub("\n", "").gsub(" ", "")
    ranges.push(range)
  end
  return ranges
end

ranges = []
query = ARGV[0]
#countries = countries()
countries = ["us", "gb"]
countries.each do |country|
  cc = country
  asn(cc).each do |asn|
    if asn["name"].include? query
      if asn["count"].to_i > 0
        puts asn
        ranges_from_asn(asn["asn"]).each do |range|
          ranges.push(range)
        end
      end
    end
  end
end

ranges.sort!
puts ranges
