- boot IP is the original address on a network interface even when the
cluster is down
- service IP is a movable IP that will be added to a network interface when
a resource group becomes online. Clients normally should connect to service
IP. If a resource group fails over to another node, service IP will be moved
there
- persistent IP comes to life when cluster is up, but it does not move to
other nodes. As the name implies, it persists to remain on the node it
should be. Persistent IPs are usually defined for maintenance purpose by
HACMP admin.
