"Well known" multicast RDNS ?

[Brandon Applegate]

So this isn't causing any issues or anything - merely curiosity.

With IPv4 - we have real delegation for 224/8 for example.  IANA gives out 
helpful answers such as .5 being OSPF:

;; ANSWER SECTION:
5.0.0.224.in-addr.arpa. 28161   IN      PTR     ospf-all.mcast.net.

;; AUTHORITY SECTION:
224.in-addr.arpa.       27293   IN      NS      b.iana-servers.net.
224.in-addr.arpa.       27293   IN      NS      c.iana-servers.net.
224.in-addr.arpa.       27293   IN      NS      ns.icann.org.
224.in-addr.arpa.       27293   IN      NS      a.iana-servers.net.

For IPv6 - there seems to be nothing of the sort.  Is there a reason 
(technical/political/historical) for this ?

Thanks.
