Big Blue is changing its IP addresses for important stuff once again, and that makes this change a High Impact/Pervasive or HIPER issue for IBM i shops. So, customers have to prepare firewalls and proxies for the upcoming infrastructure changes on IBM Fix Central system, which you can read about more at this link. Public internet IP address are changing for the IBM servers that support internet delivery of fixes and updates for customer system’s software, hardware, and operating system. Hostnames are not changing. IBM will complete the implementation of the infrastructure improvements to electronic fix distribution by March 20, 2026.
