American Registry for Internet Numbers (ARIN)

ARIN, the American Registry for Internet Numbers, is a nonprofit organization that manages and distributes Internet number resources, such as IP addresses and AS numbers, primarily for Canada, the United States, and parts of the Caribbean. It ensures these resources are allocated fairly and efficiently, facilitating the internet’s technical infrastructure. ARIN also maintains databases of these resources and supports policies for their use, helping organizations connect to the internet reliably. Essentially, ARIN acts as a steward, overseeing vital digital identifiers needed for devices and networks to communicate globally.
