  • Try https://gist.github.com/kixorz/3b172e2fc3ce35421ee9. The code is simple to adapt to Python – FelixEnescu Feb 05 '18 at 11:16

You can curl to checkip.amazonaws.com to get the public IP.

import requests
requests.get('http://checkip.amazonaws.com').text.rstrip()

Output:

52.x.147.64

import urllib3
http = urllib3.PoolManager()
response = http.request('GET', 'http://checkip.amazonaws.com')
response.__dict__

IP address found in the '_body' attribute.

Alternative solution due to:

  1. unable to use requests as it's not part of the core
  2. botocore vendored version removed by AWS found here

I would suggest:

from botocore.vendored import requests
requests.get('http://checkip.amazonaws.com').text.rstrip()

inside your lambda function.

Otherwise you may get an error that says that lambda cannot find requests unless you created your lambda from a .zip file that includes requests installed via pip

    Thanks a lot.Just like you said,I created my lambda function from a .zip file containing requests installed via pip. – Rick.Wang Jul 09 '18 at 02:28
  • This solution no longer works because the vendored version of requests has been removed from botocore. https://aws.amazon.com/blogs/developer/removing-the-vendored-version-of-requests-from-botocore/ – Khorkrak Apr 10 '20 at 14:42
  • it works but with DeprecationWarning: This dependency was removed from Botocore and will be removed from Lambda after 2021-12-01. https://aws.amazon.com/blogs/developer/removing-the-vendored-version-of-requests-from-botocore/. Install the requests package, 'import requests' directly, and use the requests.get() function instead. – SAndriy Aug 07 '21 at 20:55

Instead of import requests, you can use urllib that does not require pip.

The sample code is below;


from urllib.request import Request, urlopen


def lambda_handler(event, context):
    url = 'http://checkip.amazonaws.com'
    with urlopen(Request(url)) as response:
        print(response.read().decode('utf-8'))
