Queue manager IP subnets
This topic describes the IP subnets for queue manager network traffic in order to allow safe-listing of incoming queue manager traffic by customer-owned network firewalls.
IP Subnets of a queue manager
In order to support scalability, high availability and disaster recovery scenarios IBM® MQ as a Service runs on a flexible and dynamic set of infrastructure servers and so the IP address associated with a particular queue manager will change over time within a defined set of subnets for a particular geography.
To support users configuring network firewall rules in their on-premises or cloud environments we document the list of IP subnets for queue managers in each region at the following location;
We recommend to check the file for changes on a daily basis to avoid the risk of outages when the IP subnet ranges are updated.
