find country of ip by 17monip database local. I restruct the ipdata ,integrate same country ip during. so this module only support country code info, it is more faster. if you want to update the ip database, update the file '17monipdb.dat' and then excute change.js.

how to use

npm install 17monip
const findIp = require('17monip');
let country_code = findIp('');


how about efficiency

you can excute index.test.js

on my mac,finding 1000,000 ips only need <200ms
