AFAIK, there's nothing like that in radvd.  However, this sound like a
problem solved by mDNS (multicast DNS, also called Bonjour by Apple).  On
Linux, avahi-daemon does this.  After installing you'll need to update your
/etc/nsswitch.conf with this line...

hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4

...to make use of it.  ...but you'll need to do this on all the Linux hosts
on your network.  I think it's running by default on OSX and you can install
Bonjour on your windows hosts.

Then when a host wants to know the IP of another host running Bonjour, you
can use the .local suffix like so...

$ ping somehost.local

...or...

$ ping6 somehost.local

Thanks,
Reuben
