The ANY flag means that the application represented by the port in the member is bound to INADDR_ANY or the IPv6 unspecified address (in6addr_any). This means that in an INET (one TCP/IP stack) environment, any externally available IP address owned by that TCP/IP stack might be used to reach the target application, not just the IP address coded in this member. Therefore, there is the potential that multiple members might exist in the load balancer or other load balancers that actually represent the same application, if members were coded with the same port, protocol, and an IP address owned by the same TCP/IP stack. You need to be aware of this if you want to issue operator commands to quiesce that application. If this were the case, quiescing the application at the port level, but specifying the individual IP address of the member, might not quiesce all new workload requests to that application. Quiescing the application at the port level without specifying an IP address would be required to accomplish that task. If the application is running in a CINET (multiple TCP/IP stack) environment, any externally available IP address on the z/OS® system can be used to reach the target application, unless the application has stack affinity. If the application has stack affinity, the Advisor indicates the member is available only if the IP address coded in the member belongs to the TCP/IP stack that the application has affinity to. Line 18 in Figure 1 shows an example of this flag. For more information on the ANY flag, see z/OS Communications Server: IP System Administrator's Commands.
