I would agree with this, probably not used much.  Seems like a trivial 
thing to get delegated and set up though (unless I'm missing something).

If it is trivial (i.e. for IANA to host it) - I was just wondering why it 
was done for ipv4 and not ipv6.

The one example that came to mind would be a sniffer doing DNS lookups. 
It can be helpful sometimes to have the answer come up directly in the 
capture instead of back and forth to IANA's website.
