Techopedia Explains Internet Registry

An Internet registry is primarily responsible for allocating and assigning IP numbers to devices, websites, information systems, autonomous systems and more. There are two different types of Internet registries: regional and local.

Each region maintains its regional Internet registry (RIR) that allocates IP numbers and autonomous systems within its region or to the local Internet registry. A local Internet registry generally is an Internet service provider (ISP) that has been authorized by the RIR to assign Internet numbers to its local businesses/organizations.
