Marco, this came up, since we have to hardcode DCAE DMaaP to 10.12.25.96 in integration lab.   The suggestion if possible is to have a DNS name to point to it instead of IP.   May be it already has a DNS entry?   For example the AAI, SO, and non-DCAE DMaaP has well know DNS names and avoid us to know the IP addresses, which are different in Rackspace and Integration labs.

Feel free to redirect if not the right contact
