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?
