ip-address
ip-address is a library for validating and manipulating IPv4 and IPv6
addresses in JavaScript.
Upgrading from 9.x to 10.x
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

Examples
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'
Features
- Usable via CommonJS or ESM
