Bind 9 on more servers

[Dalibor Malek]

Hi all,

so how to start.
Ok I have 4 servers with bind 9 running, one as master and the others as 
slave.
This is working fine.

To my question:
Is it possible to have more “www” lines?
Lets say I have this in my db file:


www IN A 192.168.168.150

This means if somebody types www.mydomain.com in his browser he comes 
automatically to 192.168.168.150.
But what is if this server is down, how can I redirect him?

I thought on:

www IN A 192.168.168.150
www. IN A 192.168.168.151
www IN A 192.168.168.152

www IN A 192.168.168.153

or something like that,
When one server is down the user gets to an other server but what 
happens when all four servers are up, which one is getting the traffic.
Is something like that possible?
If yes how can I solve it?

Thank you
