ARIN, the American Registry for Internet Numbers, is a non-profit organization that manages the distribution of IP addresses in North America. These IP addresses are essential for network operations and internet connectivity. ARIN's role in ethical hacking revolves around its Whois database, a tool used to identify the owners of IP addresses.
Importance of ARIN
Network administrators and ISPs need IP addresses to operate their networks. For example, if you have a website or any internet-connected device, you need an IP address allocation from ARIN.
