Network-interfaces-plus

This module provides a single function networkInterfaces() that is a clone of Node.js’ built-in os.networkInterfaces(), enhanced to provide more information about IPv6 addresses.

In addition to the properties documented for os.networkInterfaces(), address objects where family is IPv6 get the following properties:

• temporary (boolean): true if the address is a temporary one according to RFC 4941, otherwise false
• preferred_lifetime (number): the time in seconds from now after which the address will become deprecated, 0 if expired already, 0xFFFFFFFF if infinite
• valid_lifetime (number): the time in seconds from now after which the address will become invalid, 0 if expired already, 0xFFFFFFFF if infinite

Tested on macOS, Linux, and Windows with Node.js 8.16 – 20.11. May work on other BSDs with little effort.

Most of the code is taken with minimal modification from Node.js and libuv.
