Hi Adivya,

Can you provide us more information about your installation and what
you are attempting to do?

It sounds like you booted a VM via nova on a private subnet, running
an Ubuntu image, and installed BIND in it. You then created a floating
IP address on the public subnet that points to the private subnet IP
address of the VM running BIND.

If that is the case, it could be a few issues:
1. Did you create a security group for your private subnet port on the
VM that allows DNS in? UDP port 53?
2. The dig command may be incomplete to reach your BIND server. Try
"dig -x N.N.N.N @F.F.F.F" where N.N.N.N is the IP address you want to
look up in BIND and F.F.F.F is the floating IP address you created.
