address

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();

Similar packages

Other packages similar to address

ip

The 'ip' package is similar to 'address' in that it provides utilities for IP address manipulation and querying. However, it focuses more on the manipulation and calculation of IP addresses rather than retrieving network interface details.

network

The 'network' package offers functionality to get network information such as the user's IP, MAC address, and network interfaces, similar to 'address'. However, it also includes additional features like checking internet connectivity, which 'address' does not provide.

os

While not a third-party package, Node.js's built-in 'os' module provides some overlapping functionality with 'address', such as retrieving network interfaces. However, 'address' offers more detailed and specific network information retrieval capabilities.
