Question:

What are Netflix's Aspera IP Addresses and Port Ranges?

Answer:

Netflix operates several Aspera server clusters which back many different areas of Backlot, Content Hub, and the artwork portal (Iro). Here is our list of current IP address ranges:

54.204.25.0/28 (54.204.25.0 - 54.204.25.15)
23.23.189.144/28 (23.23.189.144 - 23.23.189.159)
34.195.253.0/25 (34.195.253.0 - 34.195.253.127)

Also, if you have firewall rules on your side, you will need to open the following ports:
TCP: 22, 33001
UDP: 33001 - 33010

Please ask your IT department or network administrator to ensure that all three of the above IP address ranges are up-to-date in your whitelist/ACL, or you may experience problems sending material to or downloading from one of more of our Aspera services.
