+# IP  
+[![](https://badge.fury.io/js/ip.svg)](https://www.npmjs.com/package/ip)  
+
+IP address utilities for node.js
+
+## Installation
+
+###  npm
+```shell
+npm install ip
+```
+
+### git
+
+```shell
+git clone https://github.com/indutny/node-ip.git
+```
+  
+## Usage
+Get your ip address, compare ip addresses, validate ip addresses, etc.
+
+```js
+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'
