Frequently Asked Questions
ARIN lookup is a process to obtain contact details and addresses of organizations who owns a specific range of IP addresses.
ARIN allocates blocks of IP addresses to Local Internet Registries (LIRs) and end users for connecting devices to the internet. They ensure efficient and fair distribution of these limited resources while preventing duplication.
"ARIN" itself doesn't directly "mean" anything within an IP address. An IP address is a numerical identifier assigned to a device on the internet and doesn't contain references to organizations like ARIN.
ICANN (Internet Corporation for Assigned Names and Numbers): Focuses on global internet governance, specifically managing the Domain Name System (DNS) and coordinating top-level domains (TLDs) like .com, .org, and country-specific domains like .fr or .in. They also oversee policies for domain name registration and address disputes. On the other hand, ARIN (American Registry for Internet Numbers): Manages internet number resources in North America, including allocating and distributing IP addresses and Autonomous System Numbers (ASNs). They contribute to global policy development but primarily focus on local resource management and technical services.
