Function retrieving AWS Lambda public IP address. Copy and paste this to your Lambda console, use standard permissions, execute and observe the log to see the public IP address of your Lambda function.

aws_lambda_public_ip.js

var http = require('http');

exports.handler = function(event, context) {
	http.get('http://httpbin.org/get', function(res) {
		var body = '';
		res.on('data', function(chunk) {
			body += chunk;
		});
		
		res.on('end', function() {
			console.info(body);
			context.done(null);
		});
	}).on('error', function(e) {
		console.error(e.message);
		context.fail(null);
	});
};

@kixorz I'm just curious, does this change on every execution?

It may change. It depends if the Lambda function remains on the same machine "warmed up".

thanks @kixorz
btw for python dudes out there, it's:
requests.get('http://checkip.amazonaws.com').text.rstrip()

also, is there a way to provide the lambda with an ip (the user's) to act from ?
or make sure lambda really randomize / change ip's all the time ?

Thanks again man

For the dedicated IP 1) you could have the lambda use a proxy 2) you can have the lambda deployed to a vpc and use some gateway or proxy For the randomization - there is no way to do that with lambda public ips

you don't have to move those bytes yourself.

Axios

does this code assure us that lambda function uses different IP addresses for scrapping to avoid being blocked by Captcha? thanks

Axios is a pretty cool library, but this code is on purpose free of third party libraries.

@lydiahelkinz This code only tells you what the current public IP of the Lambda is.

If you're looking at scraping, you should consider using a good proxy service, implement a proxy layer in your code and block certain tracking requests.

can i use lambda function without going through proxy services

@lydiahelkinz Yes, you can. Depends on what you're scraping. On some sites you will be very successful, on others it will fail. If you hit sites running on say CloudFlare or a similar CDNs with adaptive firewalls and bot protections, you will need to advance your game as the default Lambdas won't be enough. You may still use Lambdas as your compute platform, but the HTTP handling and network access will need to be more advanced.
