another usage is to know the name of the machine which is sending rogue
RA (this happens too many times in conference environment).

There are actually 2 different usage of multicast. What you are describing is
multicast when the subject is an IP address. The other case is multicast
when the subject is a name and you're looking for an IP address.
This second case is the one I do not think is that useful.
