S3 Storage Access

Almost every corporate firewall will allow outgoing access to the web at ports 80 and/or 443, or via an HTTP/HTTPS proxy. Can you access https://s3.amazonaws.com from behind the firewall? If so, you can access S3 storage.

Localization

For specific access at a corporate location behind a firewall needing an IP range, please try these steps.

1. From a command prompt use dig or nslookup to lookup an IP for s3.amazonaws.com

2. Take the IP you get (I get 207.171.187.117) and run a whois query on it. If you aren't on a system that has whois installed there are several websites that provide it, including Network Solutions at http://www.networksolutions.com/whois/index.jsp

3. On there you will see the range of IP addresses Amazon owns around the IP that you found. So for me, when I whois the above IP the following result comes back:

“Amazon.com, Inc. AMAZON-01 (NET-207-171-160-0-1) 207.171.160.0 – 207.171.191.255”

NOTE: s3.amazonaws.com is a CNAME for s3-1.amazonaws.com and s3-2.amazonaws.com

The two ranges of IPs I see assigned for these are:
72.21.192.0 – 72.21.223.255
207.171.160.0 – 207.171.191.255

You might get completely different IP ranges based on where you are in the world. Just follow these steps to localize.
