We will be adding the following new IP range to our Aspera services:
188.8.131.52/25 (184.108.40.206 - 220.127.116.11)
Aspera servers hosted by Netflix will begin using IP addresses in this range beginning on Monday, January 23, 2017. If your network requires whitelisting of Aspera IP address, please be sure to have your IT department update your firewall or network device before this date.
Please note that this is an expansion, not a migration. We will not be removing any of our existing IP address ranges.
All of Netflix's Aspera IP address range and port information can be found here.
