Public internet IP address and hostnames will be changing for the IBM servers that support internet delivery of fixes and updates for your system’s software, hardware, and operating system.
This means you may need to perform some changes to your enterprise firewall configuration to ensure uninterrupted fix delivery services. New network connections between your machine and IBM servers are required to keep your ability to order and download fixes and updates for your system’s software, hardware, and operating system. You must configure your firewall and proxy server if you have a firewall in your network, or if your machine must use a proxy server to access the internet.
