node-ec2-publicip

Retrieve EC2 public-ipv4 from instance metadata.

Note: this assumes that a metadata service is available at http://169.254.169.254/. Thus it works on EC2 instances, behavior on other machines is undefined.

Install

    npm install ec2-publicip

Example

    var ec2 = require("ec2-publicip");

    ec2.getPublicIP(function (error, ip) {
    	if (error) {
    		console.log(error);
    	}
        console.log("Instance Public IP: ", ip);
    });
