ICANN governs registries

InterNIC gave way to ICANN which manages top level domain names and assignments of address blocks to registries.

 
 

Addendum 5/14/2018: InterNIC used to tell you what domain name pointed where before everyone started using routers to crowdsource as much.

 
 

Addendum 7/20/2019:The NIC part of InterNIC stood for Network Information Center and ICANN is Internet Corporation for Assigned Names and Numbers.
