Package Exports

ipv6
ipv6/lib/node/bigint

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ipv6) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

javascript-ipv6

javascript-ipv6 is a library for manipulating IPv6 addresses in JavaScript.

Examples

For node:

var v6 = require('ipv6').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"

For a browser:

<!DOCTYPE html>
<html lang="en">
 <head>
  <title>Simple IPv6 test</title>

  <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

  <script type="text/javascript" src="/lib/jsbn.js"></script>
  <script type="text/javascript" src="/lib/jsbn2.js"></script>

  <script type="text/javascript" src="/lib/sprintf.js"></script>

  <script type="text/javascript" src="/ipv6/ipv6.js"></script>

  <script type="text/javascript">
   $(function() {
    var address6 = new v6.Address('a::b');

    $('#output').text(address6.canonicalForm());
   });
  </script>
 </head>

 <body>
  The canonical form of <code>a::b</code> is: <code id="output"></code>
 </body>
</html>

Current functionality

Parsing of most IPv6 notations
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
Unit tests with node.js and Mocha

Used by

Rackspace in node-swiz
node-socksified

Future functionality

Investigate procstreams for the CLI tool
Base 64/85 encoding?
Reverse lookups? (Whether a domain name has IPv6 glue)
