Effective February 16, 2016, Amazon is changing how they handle AS2 files to include new IP address ranges. AS2 is a protocol for secure, direct connection.
Amazon has long used a range of IP addresses. Typically, a vendor’s AS2 system caches the IP address. However, to add new IP addresses a restart generally is needed.
Here are your two key action items:
1. Make sure your firewall or network administrator has the firewall rules set to allow/whitelist all the IP numbers in the range, they should be able to continue.
2. Trigger a system to restart.
The distinct IP address ranges are:
• 107.21.95.224/27
• 107.21.95.192/27
Note: you may also need to open port 80 if you filter outbound traffic.
Caution: If a vendor’s firewall rules do not currently allow the present and new IP numbers in the range, then hard stop will occur on February 16. A hard stop means no orders arrive.
