In a short answer... No.
DNS is only for translating a host-name into an IP address.
It can return an IP address as a round-robin, regardless of whether the
server on that address is up, down, unavailable, non-existent.
What you're asking for in essence is clustering.
You'll be needing something else in your software like Heartbeat/Nagios
to monitor nodes status and take action based on when a node goes down
to take it out of the cluster.
