failover resolution

Hi,

Is it possible, with NDS, to have, something like a failover for the name
resolution
i.e.
NAME1 @IP1
NAME2 @IP2
NAME3 @IP3
and
alias  NAME  which is NAME1,
                            or NAME2 if NAME1 not responding
                            or NAME3 if NAME1 and NAME1 not responding
                            etc...
or any product  which can do that ?
