Actually, I believe that the IANA primarily defines new SNMP MIBs. It
also assigns TCP and UDP port numbers and various other kinds of
Internet identifiers. As you pointed out, it has rarely ever allocated
IP addresses directly preferring to delegate that work to the InterNIC
and the RIRs. 

I just wanted to emphasize that the IANA has a much broader role than
just being the top-level of the IP address allocation hierarchy. Mind
you, it was over 10 years ago when I was told about the volume of work
being mostly MIB definitions. It may have changed since then.
