There is a way to tell bind to listen on a specific IP

options {
        listen-on {; };

The only problem here is that if I want to run a secondary DNS on IP I can not. There is also an option to bind multiple IP
addresses in bind I tried this also yet the vserver only binds to the first
IP :(

Kinda sucks cause it would be nice to have primary and secondary on the same

Not sure. There is a flaw in vserver kernel. If you do /sbin/ifconfig
from a vserver, you see all the devices, but you only see the IP for the
device/aliases you own.

The flaw is that /proc/net/dev is not filtered out. The ioctl used to
IP addresses assign to a device is properly protected. So on one side, you
see something and on the other side, you can't retrieve information about

I suspect this is confusing named. Is there a way in named to specify
on which IP to bind instead of letting it do it all by itself. Normally,
is setting one socket per IP it finds and I suspect it gets confused when
it can extract the IP of a device.
