My application runs behind a fire wall and my IT department has asked me to provide a list of ip addresses that my application needs access to. When i nslookup api.themoviedb.org i get several results like this:

Non-authoritative answer:
api.themoviedb.org  canonical name = tm-api-prod-789738748.us-east-1.elb.amazonaws.com.
Name:   tm-api-prod-789738748.us-east-1.elb.amazonaws.com
Address: 54.225.223.192

So it seems that the api is hosted in the amazon cloud. I had a similar issue with the search results and accessing images stored in amazon cloud front. For cloudfront I was able to find this list of ip address ranges: https://forums.aws.amazon.com/ann.jspa?annID=2051

I searched the amazon aws faq to see if there was a similar list for aws but had no luck.

Can you provide any insight into how the ip addresses for the api are configured?

Thanks!
