IP Filter: A light-weight IP address based filtering system

This package provides easy IP based access control. This can be achieved either by blacklisting certain IPs and whitelisting all others, or whitelisting certain IPs and blacklisting all others.

Version

0.0.10

Installation

Recommended installation is with npm. To add node-ipfilter to your project, do:

npm install express-ipfilter

Usage with Express

Blacklisting certain IP addresses, while allowing all other IPs:

// Init dependencies
var express = require('express')
    , ipfilter = require('ipfilter')
    , app = express.createServer()
    ;

// Blacklist the following IPs
var ips = ['127.0.0.1'];

// Create the server
app.use(ipfilter(ips));
app.listen(3000);

Whitelisting certain IP addresses, while denying all other IPs:

// Init dependencies
var express = require('express')
    , ipfilter = require('ipfilter')
    , app = express.createServer()
    ;

// Blacklist the following IPs
var ips = ['127.0.0.1'];

// Create the server
app.use(ipfilter(ips, {mode: 'allow'}));
app.listen(3000);

Using CIDR subnet masks for ranges:

var ips = ['127.0.0.1/24'];

// Create the server
app.use(ipfilter(ips, {mode: 'allow'}));
app.listen(3000);

Using IP ranges:

var ips = [['127.0.0.1','127.0.0.10']];

// Create the server
app.use(ipfilter(ips, {mode: 'allow'}));
app.listen(3000);
