Grid version : 11.2.0.3
Guest OS           : Oracle Enterprise Linux 6 (64-bit )
Host OS           : Windows 7 (64-bit )
Hypervisor : Virtual Box 4.1.18


I am planning to install 11.2 RAC on OEL VMs created in my Laptop.

My Laptop's Host OS is Windows 7 and its IP address is determined by the Wireless router when connected to the internet. (ie. All the time )


When connected to the Wireless router, the IP address of my Host system is : 192.168.0.101
Ipconfig output shown below
Wireless LAN adapter Wireless Network Connection:

   Connection-specific DNS Suffix  . :

When disconnected from the internet, the IP is 169.254.17.206

IPCONFIG output when not connected to the internet through wireless router

I want the RAC configuration to work even if my laptop is not connected to internet. So, shouldn't I be creating a
Static IP for my Host OS (Windows 7) ? If i have to assign a static IP to my Host OS (Windows 7) what IP should I be assigning ?
