What's IP Address Handling Libraries?

These libraries are designed to assist developers in retrieving and managing IP addresses in Node.js applications. They provide functionalities to extract the client's IP address from requests, handle various scenarios such as proxies and load balancers, and ensure accurate identification of the user's IP address. This is crucial for applications that require geolocation, security features, or analytics based on user location.

Feature Comparison: ip vs request-ip vs ipware

IP Address Retrieval

  • ip:

    The 'ip' package provides functions to validate and manipulate IP addresses, but does not directly handle retrieval from requests. It focuses on operations like checking if an address is valid or converting between formats.

  • request-ip:

    'request-ip' is specifically designed to extract the client's IP address from the request object in Express.js applications, handling various proxy scenarios seamlessly.

  • ipware:

    'ipware' excels in accurately retrieving the client's IP address from the request, considering various headers such as 'X-Forwarded-For' and 'X-Real-IP', making it suitable for applications behind proxies.

Proxy Handling

  • ip:

    This package does not inherently manage proxy scenarios; it is more focused on IP manipulation and validation.

  • request-ip:

    'request-ip' automatically checks for common headers used by proxies to retrieve the original client IP, making it effective in proxy-heavy environments.

  • ipware:

    'ipware' is built to handle IP retrieval in environments with proxies, ensuring that the correct client IP is extracted even when multiple proxies are involved.

Ease of Use

  • ip:

    The 'ip' package is simple to use for IP-related operations but requires additional logic to handle IP retrieval from requests.

  • request-ip:

    'request-ip' is very easy to implement as middleware in Express.js, requiring minimal setup to start retrieving client IPs.

  • ipware:

    'ipware' offers a straightforward API for retrieving the client's IP address, making it easy to integrate into applications without complex configurations.

Performance

  • ip:

    Performance is generally good for IP manipulation tasks, but it is not optimized for high-frequency IP retrieval from requests.

  • request-ip:

    'request-ip' is lightweight and performs well in typical web applications, efficiently handling IP retrieval without significant overhead.

  • ipware:

    'ipware' is optimized for performance when extracting IP addresses, ensuring quick access even in high-load scenarios.

Documentation and Community Support

  • ip:

    The 'ip' package has decent documentation but may lack extensive community support compared to more popular libraries.

  • request-ip:

    'request-ip' benefits from being part of the Express ecosystem, with comprehensive documentation and strong community support, making it easy to find resources and examples.

  • ipware:

    'ipware' has good documentation and is well-supported in the community, making it easier to find examples and troubleshooting help.

How to Choose: ip vs request-ip vs ipware
  • ip:

    Choose 'ip' if you need a straightforward utility for IP address manipulation and validation, focusing on IPv4 and IPv6 addresses without additional dependencies or complexity.

  • request-ip:

    Select 'request-ip' if you require a simple middleware solution specifically for Express.js applications, designed to easily retrieve the client's IP address from the request object, particularly in scenarios involving multiple proxies.

  • ipware:

    Opt for 'ipware' if your application needs to reliably extract the client's IP address from various sources, including handling proxies and ensuring accuracy in different environments.

Usage

Get your ip address, compare ip addresses, validate ip addresses, etc.

var ip = require('ip');

ip.address() // my ip address
ip.isEqual('::1', '::0:1'); // true
ip.toBuffer('127.0.0.1') // Buffer([127, 0, 0, 1])
ip.toString(new Buffer([127, 0, 0, 1])) // 127.0.0.1
ip.fromPrefixLen(24) // 255.255.255.0
ip.mask('192.168.1.134', '255.255.255.0') // 192.168.1.0
ip.cidr('192.168.1.134/26') // 192.168.1.128
ip.not('255.255.255.0') // 0.0.0.255
ip.or('192.168.1.134', '0.0.0.255') // 192.168.1.255
ip.isPrivate('127.0.0.1') // true
ip.isV4Format('127.0.0.1'); // true
ip.isV6Format('::ffff:127.0.0.1'); // true

// operate on buffers in-place
var buf = new Buffer(128);
var offset = 64;
ip.toBuffer('127.0.0.1', buf, offset);  // [127, 0, 0, 1] at offset 64
ip.toString(buf, offset, 4);            // '127.0.0.1'

// subnet information
ip.subnet('192.168.1.134', '255.255.255.192')
// { networkAddress: '192.168.1.128',
//   firstAddress: '192.168.1.129',
//   lastAddress: '192.168.1.190',
//   broadcastAddress: '192.168.1.191',
//   subnetMask: '255.255.255.192',
//   subnetMaskLength: 26,
//   numHosts: 62,
//   length: 64,
//   contains: function(addr){...} }
ip.cidrSubnet('192.168.1.134/26')
// Same as previous.

// range checking
ip.cidrSubnet('192.168.1.134/26').contains('192.168.1.190') // true


// ipv4 long conversion
ip.toLong('127.0.0.1'); // 2130706433
ip.fromLong(2130706433); // '127.0.0.1'
