address

Get current machine IPv4, IPv6, MAC and DNS servers.

DNS servers receive from /etc/resolv.conf.

Install

npm install address

Usage

Get IP is sync and get MAC is async for now.

esm & typescript

import { ip, ipv6, mac } from 'address';

// default interface 'eth' on linux, 'en' on osx.
ip();   // '192.168.0.2'
ipv6(); // 'fe80::7aca:39ff:feb0:e67d'
mac(function (err, addr) {
  console.log(addr); // '78:ca:39:b0:e6:7d'
});

// local loopback
ip('lo'); // '127.0.0.1'

// vboxnet MAC
mac('vboxnet', function (err, addr) {
  console.log(addr); // '0a:00:27:00:00:00'
});

commonjs

const { ip, ipv6, mac } = require('address');

// default interface 'eth' on linux, 'en' on osx.
ip();   // '192.168.0.2'
ipv6(); // 'fe80::7aca:39ff:feb0:e67d'
mac(function (err, addr) {
  console.log(addr); // '78:ca:39:b0:e6:7d'
});

// local loopback
ip('lo'); // '127.0.0.1'

// vboxnet MAC
mac('vboxnet', function (err, addr) {
  console.log(addr); // '0a:00:27:00:00:00'
});

Get all addresses: IPv4, IPv6 and MAC

esm & typescript

import { address } from 'address';

address((err, addrs) => {
  console.log(addrs.ip, addrs.ipv6, addrs.mac);
  // '192.168.0.2', 'fe80::7aca:39ff:feb0:e67d', '78:ca:39:b0:e6:7d'
});

address('vboxnet', (err, addrs) => {
  console.log(addrs.ip, addrs.ipv6, addrs.mac);
  // '192.168.56.1', null, '0a:00:27:00:00:00'
});

commonjs

const { address } = require('address');

address((err, addrs) => {
  console.log(addrs.ip, addrs.ipv6, addrs.mac);
  // '192.168.0.2', 'fe80::7aca:39ff:feb0:e67d', '78:ca:39:b0:e6:7d'
});

address('vboxnet', (err, addrs) => {
  console.log(addrs.ip, addrs.ipv6, addrs.mac);
  // '192.168.56.1', null, '0a:00:27:00:00:00'
});

Get an interface info with family

esm & typescript

import { getInterfaceAddress } from 'address';

getInterfaceAddress('IPv4', 'eth1');
// { address: '192.168.1.1', family: 'IPv4', mac: '78:ca:39:b0:e6:7d' }

commonjs

const { getInterfaceAddress } = require('address');

getInterfaceAddress('IPv4', 'eth1');
// { address: '192.168.1.1', family: 'IPv4', mac: '78:ca:39:b0:e6:7d' }

Get DNS servers

esm & typescript

import { dns } from 'address';

dns((err, servers) => {
  console.log(servers);
  // ['10.13.2.1', '10.13.2.6']
});

commonjs

const { dns } = require('address');

dns((err, servers) => {
  console.log(servers);
  // ['10.13.2.1', '10.13.2.6']
});

Promise style apis

import { address, mac, dns } from 'address/promises';

const addr = await address();
const macAddress = await mac();
const servers = await dns();
