The American Registry for Internet Numbers (ARIN) is a nonprofit, member-based organization that supports the operation of the Internet through the management and distribution of Internet number resources. These resources include Internet Protocol (IP) addresses (both IPv4 and IPv6) and Autonomous System Numbers (ASNs). ARIN serves a specific geographic region: Canada, the United States, and many Caribbean and North Atlantic islands. ARIN facilitates policy development by its community, provides registration services, and plays a key role in Internet governance and education related to number resources.
