I still prefer having different IP addresses for different IOCs on the

when things are hanging and you want to know which of the soft IOCs has
to be rebooted.

How do you get the IOC (which still uses the old RSRV server, not CAS)
to bind to only one particular IP address?
RSRV doesn't make use of the EPICS_CAS_INTF_ADDR_LIST variable for
anything other than its CA beacon addresses, it still listens for client
connections on all interfaces it can find. If those interfaces are on
different subnets then this won't generally be a problem (except for
client programs that are running on that same machine), but for two IPs
on the same subnet this ought to give "duplicate PV" errors to all
clients that try to connect to that IOC.
Am I missing something?
