IPI (IP-Info)

A free library/cli tool to get IP information.

Performance

Due to the nature of libraries used (SQLite3, IP2Location), this project is seemingly littered with synchronous operations.

Despite this, this project still delivers reasonable runtime performance that beats using an API.

Benchmarks: (not quite accurate, tested on my development machine)

| test | duration | | ----------- | -------- | | require() | 44.36 ms | | ipi() | 0.066 ms |

An extreme solution to the blocking API is wrapping the API with piscina.

Maintenance

You might want to update the databases library from time to time. Databases will be updated usually every month (No guarantees 😅️)

npm i @e9x/ipi-databases@latest

API

Example:

import ipi from "@e9x/ipi";

const ipInfo = ipi("69.42.0.123");
console.log(ipInfo);

{
  success: true,
  asn: 11404,
  asd: 'AS-WAVE-1',
  city: 'San Francisco',
  region: 'California',
  zipCode: '94102',
  timezone: '-08:00',
  latitude: 37.774929,
  longitude: -122.419418,
  countryLong: 'United States of America',
  countryShort: 'US'
}

If you need to access the IPInfo type (TypeScript):

import ipi, { IPInfo } from "@e9x/ipi";

const whatever: IPInfo = ipi("69.42.0.123");

console.log(whatever);

CLI

Install the CLI tool globally:

$ npm install --location=global @e9x/ipi

If you encounter a read/write error when running the tool after installing globally on Linux, refer to https://github.com/sindresorhus/guides/blob/main/npm-global-without-sudo.md

The CLI syntax is as follows:

Usage: ipi <IP>

  city: 'Las Vegas',
  region: 'Nevada',
  zipCode: '89136',
  timezone: '-07:00',
