Just to get you right:
* You have 10 say "domains" running on 5 realservers.
* If one domain dies you like to  bring up a "sorry-Page" that is 
individual for every domain.

If these guesses are your intention then you will have to use 10 
different IPs on the seperate fallback-Server mapped via the http-daemon 
to your individual sorry-sites.

The loadbalancing daemon ldirectord, or keepalived, or ipvsmand knows 
when the last real server of the domain is dead and
directs the inkoming IP packets now to the sorry-server IP. But it can 
not change them to an other URL/domain since this information is 
encapsulated in the Package HTTP-Protocol content.

If the many IPs itself are your problem (limited number) you may use 
different Ports on the same IP. But the configuration
overhead will remain the same.

Best Regards,

Volker
