ip-address is a library for validating and manipulating IPv4 and IPv6
addresses in JavaScript.
The dependency on jsbn was removed thanks to
michal-kocarek. Thanks Michal! For
clarity, all methods with BigInteger in the name were renamed to BigInt.
#### Breaking changes
- #fromBigInteger() → #fromBigInt(); now returns a native BigInt
- #bigInteger() → #bigInt(); now returns a native BigInt
Documentation is available at ip-address.js.org.
``js
var Address6 = require('ip-address').Address6;
var address = new Address6('2001:0:ce49:7601:e866:efff:62c3:fffe');
var teredo = address.inspectTeredo();
teredo.client4; // '157.60.0.1'
`
- 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.
- Works in node and the browser (with browserify)
