ip-address

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

Documentation

Documentation is available at ip-address.js.org.

Examples

var Address6 = require('ip-address').Address6;

var address = new Address6('2001:0:ce49:7601:e866:efff:62c3:fffe');

address.isValid(); // true

var teredo = address.inspectTeredo();

teredo.client4;    // '157.60.0.1'

Features

• Parsing of all IPv6 notations
• Parsing of IPv6 addresses and ports from URLs with Address6.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 and the browser (with browserify)
• ~1,600 test cases
