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. The topic is only applicable to multi-tenant plans.

IP Subnets of a queue manager

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, the following list gives IP subnets for queue managers in json format:
