Setting up a backup server

[Hiten Patel]

Hi,

I would like to setup a backup webserver that is accessed when the first
webserver is down.
ie
111.111.111.111 webserver one
222.222.222.222 webserver two (mirror of web server one)

 www.domain.com on 111.111.111.111 is redirected to 222.222.222.222, when
webserver one is down.

I want webserver two on 222.222.222.222 to be accessed ONLY when webserver
one is not available.
At all other times the webserver two is online but not being access
(redundant backup).

I thing this is possible using round robin DNS but have now idea how to set
this up, the howto's I have
seen all mention that both servers are accessed.

is it possible to do this with bind 9.

hope someone can help me
