Because Raspberry Pi is placed at home, due to ISP reasons, public IP keeps changing. How can we quickly get the current network’s public IP?

Today introduce a small tool that can simply get public IP.

public-ip

Installation

npm install --save public-ip

Usage

const publicIp = require('public-ip');
 
publicIp.v4().then(ip => {  
    console.log(ip);
    //=> '46.5.21.123' 
});
 
publicIp.v6().then(ip => {
    console.log(ip);
    //=> 'fe80::200:f8ff:fe21:67cf' 
});

Set HTTPS

If using https, it will query based on icanhazip.com service.

Relatively safer, but also slightly slower.

publicIp.v4({
    https:true   // Default false
}).then(ip => {  
    console.log(ip);
    //=> '46.5.21.123' 
});

Set Timeout

publicIp.v4({
    timeout:5000   // Default 5000 milliseconds
}).then(ip => {  
    console.log(ip);
    //=> '46.5.21.123' 
});
