local-ipv4-address
Get the local network IPv4 address of the current computer based on the default gateway.
All of the other Node.js modules I found picked the address of the first or a random external interface from os.networkInterfaces()
or performed a DNS lookup on the hostname. What if I have VMware virtual interfaces, an OpenVPN connection, wifi, an ethernet cable, and some loopback interfaces with convincing-looking hosts entries all connected?
Under the hood, it just executes route.exe
or netstat
and parses the output with regular expressions.
Installation
$ npm install --save local-ipv4-address
Usage
In a Node module
var localIpV4Address = require("local-ipv4-address");
localIpV4Address().then(function(ipAddress){
console.log("My IP address is " + ipAddress);
// My IP address is 10.4.4.137
});
On the command line
$ node node_modules/local-ipv4-address
10.4.4.137
