load balancing...

[arvind rao]

Hi all,

  I am new to DNS admin and I need some help on load
balancing.

  I need to setup one domain-name for 2 IP addresses
such that if one of the machines are not up, it should
automatically pick the other one.
  What I saw with having just 2 "A" record entries in
the named.domain-name/IPnetwork file was that if I try
to ping the "domain-name", it randomly picks one of
the 2 IP'S and if it picks the IP address of the
machine which is down, then it just doesnt
automatically try the other machine. How do I set it
up so that it identifies the other machine if one
machine is down. 
  Is there a way to set priority level????

Kindly help....

Thanks
Arvind
