ip-address

ip-address is a library for manipulating IPv6 and IPv4 addresses in JavaScript.

Examples

For node:

var v6 = require('ip-address').v6;

var address = new v6.Address('2001:0:ce49:7601:e866:efff:62c3:fffe');

console.log(address.isValid()); // Prints "true"

var teredo = address.teredo();

console.log(teredo.client4);    // Prints "157.60.0.1"

Current functionality

• Parsing of most IPv6 notations
• Parsing of IPv6 Addresses and Ports from URLs with v6.Address.fromURL(url)
• Validity checking
• Decoding of the Teredo information in an address
• Whether one address is a valid subnet of another
• What special properties a given address has (multicast prefix, unique local address prefix, etc.)
• Number of subnets of a certain size in a given address
• Display methods
  • Hex, binary, and decimal
  • Canonical form
  • Correct form
  • IPv4-compatible (i.e. ::ffff:192.168.0.1)
• Works in node.js and the browser (with browserify)
• 1,500+ unit tests with node.js and Mocha
