Do we need any considerations of multiple IP addresses on each host?
We don't think we need anything special for Policy Stores, User Stores, Policy Servers, or WebAgents as long as TCP/IP connections can be established among them.
We'd like to confirm it.
Actually every host has two IP addresses from the beginning when it is connected to the network. One is 127.0.0.1 for localhost and the other is for connecting to other hosts. Both IP addresses can be used along with your purpose. It is the same when the host has more IP addresses.
