If one were to ignore layer 9 politics, it could be argued the  
authority/delegation models between DNS and address space are quite  


IANA maintains "." ("dig . axfr") and delegates portions  
of the namespace to top-level domain registries
Top-level domain registries delegate parts of their namespaces to  
second-level domain registries (typically end users)

Address space:

IANA maintains the top-level address registry ( 
assignments) and delegates portions of the address space to RIRs.
RIRs delegate parts of their address space to LIRs/ISPs/end users.

Of course, ignoring layer 9 politics can be a bit challenging.
