If you just get a list of IP addresses with no other DNS records to indicate which is which, you can use any of them for the VIP. In that sense, they are interchangable. Once you choose which ones are the VIP and which are the public IPs, those decisions are set in stone and cannot be changed.

That's what I meant. Hope it didn't confuse anyone.

They definitely are not interchangeable. The VIP is going to flip between nodes and is managed by the clusterware.  Did the SYSADMIN set up /etc/hosts for you? I'd check there first as that's where you should put all  IP
VIP
PRIvate entriees on every node 

nslookup should help you resolve which is the IP and which is the VIP. You could always ask the system administrator.

Hi

VIP and PUBLIC IP must be in same network so that might give you a hint

Private IP should be something like 192.168.*.* or 10.*.*.*

Thanks

Hi

Public IP is for the server (like any other server physical IP)
VIP for Database access (provides Failover and Failback if configured) and must be in the same subnet as Public IP
Private IP for Clusterware heartbeat and RAC Cache Fusion
