Introduction to in-ip

The in-ip library is a robust and versatile tool for handling various IP-related functionalities in web and network applications. This article provides an extensive overview of the in-ip APIs, demonstrating how to utilize these APIs effectively.

In-ip API Examples

1. Retrieve Client IP

  const getClientIP = () => {
    return inIp.getIPFromRequest(request);
  };

2. Validate IP Address

  const isValidIP = (ip) => {
    return inIp.validateIP(ip);
  };

3. Get IP Information

  const getIPInfo = async (ip) => {
    const info = await inIp.getIPInfo(ip);
    console.log(info);
  };

4. Convert IP to Binary

  const ipToBinary = (ip) => {
    return inIp.convertToBinary(ip);
  };

5. Get IP Range

  const getIPRange = (ip, subnet) => {
    return inIp.calculateIPRange(ip, subnet);
  }

6. Check IP against CIDR

  const isIPInCIDR = (ip, cidr) => {
    return inIp.isIPWithinCIDR(ip, cidr);
  }

Building an Application with in-ip

Here’s a simple application example that uses multiple in-ip APIs:

  const inIp = require('in-ip');

  // Retrieve client IP
  const clientIP = inIp.getIPFromRequest(request);

  // Validate the client IP
  if (inIp.validateIP(clientIP)) {
    // Get IP Info
    inIp.getIPInfo(clientIP).then(info => console.log(info));

    // Convert client IP to Binary
    const binaryIP = inIp.convertToBinary(clientIP);
    console.log(`Client IP in Binary: ${binaryIP}`);

    // Check IP against CIDR
    const isInRange = inIp.isIPWithinCIDR(clientIP, '192.168.0.0/16');
    console.log(`Is client IP within the CIDR range: ${isInRange}`);
  }
  else {
    console.log('Invalid IP Address');
  }

This example demonstrates the usage of multiple in-ip APIs to retrieve, validate, and manipulate IP addresses effectively.
