@taktikorg/labore-fugiat-neque

@taktikorg/labore-fugiat-neque is a library for validating and manipulating IPv4 and IPv6 addresses in JavaScript.

Migrating from 6.x to 7.x

@taktikorg/labore-fugiat-neque was rewritten in TypeScript for version 7. If you were using version 6 you'll need to make these changes to upgrade:

• Instead of checking isValid(), which has been removed, you'll need to use a try/catch if you're accepting unknown input. This made the TypeScript types substantially easier as well as allowed the use of an AddressError class which will contain a parseMessage if an error occurred in the parsing step.
• Instead of using the error, parseError, and valid attributes you'll need to use the message and parseMessage of the thrown AddressError.

Documentation

Examples

var Address6 = require('@taktikorg/labore-fugiat-neque').Address6;

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

var teredo = address.inspectTeredo();

teredo.client4;    // '157.60.0.1'

Features

• Usable via CommonJS or ESM
• 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
