I see that too!

It is the Node Information Query multicast address. You probably didn't 
find an official register for it because the definition of the address 
has changed since implementation. Looking at the code you'll see a 
reference to draft-ietf-ipngwg-icmp-name-lookup-04 in in6_ifattach.c.

In the draft 04 version the NI mcast address is formed from the prefix 
ff02::2:0:0/96 and a digest. That all changed and in the RFC4620 it is 
using ff02::2:ff00:0/104 and a different digest.

http://tools.ietf.org/html/rfc4620

Hope this helps!
