I've a question that I've been unable to find an answer for. We're in the process of updating our app to make use of push notifications. We have been given a production push URL of cpxxx.pushapi.na.blackberry.com, however our firewall cannot filter on domain name and we need IP addresses. Is there an IP address, or range of IP addresses, that we can be sure won't change and break our service.
