About ARIN
The American Registry for Internet Numbers (ARIN) is the nonprofit corporation that manages the distribution of all IPv4 & IPv6 addresses in the United States, Canada, and many Caribbean and North Atlantic Islands. An ARIN search reveals who owns a specific IP address and how to contact them. This information is publicly accessible to anyone with your IP address — every website you visit can potentially log and use it. For privacy, we recommend using a VPN to hide your IP.
