Advanced tools
Package description
The 'address' npm package is a utility for retrieving detailed information about the network interfaces of the host machine. It can be used to get IP addresses, MAC addresses, and DNS servers, among other things. This package is particularly useful for applications that need to be aware of the network configuration of the host they are running on.
Get IP Address
This feature allows you to retrieve the IPv4 or IPv6 address of the host machine. It's useful for applications that need to know their own IP address, for instance, to communicate with other services in a network.
const address = require('address');
// Get the IPv4 address
address.ip(); // '192.168.0.2'
// Get the IPv6 address
address.ipv6(); // 'fe80::7ca0:ab22:703a:b329'Get MAC Address
This feature enables you to get the MAC address of the host machine. This can be useful for applications that need to identify the network interface of the host.
const address = require('address');
// Get the MAC address
address.mac(function (err, addr) {
console.log(addr); // '78:ca:39:b0:e6:7c'
});Get DNS Servers
This feature provides the DNS servers configured on the host machine. It's useful for applications that need to perform DNS lookups or need to know about the network's DNS configuration.
const address = require('address');
// Get DNS servers
console.log(address.dns()); // ['8.8.8.8', '8.8.4.4']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.
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.
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.
Readme
Get current machine IPv4, IPv6, MAC and DNS servers.
DNS servers receive from /etc/resolv.conf.
npm install address
Get IP is sync and get MAC is async for now.
