App Maker: Public facing IP for UrlFetch?

Question

What are the public facing IP addresses, when app maker calls an external service with urlfetch?

My external service insists on white-listing these. Is there a public list available from google?

Within App Maker, I want to use the UrlFetch to call an external service, very much like the App maker sample.

I see there is a list of Apps Script's IP address ranges for the JDBC. Would this be the same ranges? (https://developers.google.com/apps-script/guides/jdbc#accessing)

Thanks in advance, John

I had the same issue, may be you can try the "useIntranet" option which may reduce the ipaddress range within your websites/webapps current network

https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app

eg:

var response = UrlFetchApp.fetch("https://Url.com",{
  'method' : 'post',
'payload' :{ 
'useIntranet':true,
'key':"value"
}
}
);
