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

``bash
npm install ec2-publicip
`

Example

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

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