IP WHOIS Lookup

IP WHOIS Lookup: Find Out Who Owns an IP Address 🕵️‍♂️

Want to know who’s behind an IP address or domain? Our IP WHOIS lookup tool makes it easy to dig up publicly available registration and contact information. Just pop in the IP address or domain name, and you’ll get details that can include the registered owner, their contact information (often for network abuse), location, and the organization responsible for managing that IP block or domain. For IP addresses, the information typically comes from one of the five Regional Internet Registries (RIRs).

You’ll see what our tool can find, which often includes how many IPs are in an assigned block and how to report abuse if needed. Whether you’re tracing spam, investigating suspicious network activity, or just curious about internet infrastructure, this tool aims to provide the facts.

What Are Regional Internet Registries (RIRs)?

The internet's IP addresses and Autonomous System Numbers (ASNs) are managed globally by the Internet Assigned Numbers Authority (IANA). IANA delegates the allocation of these resources to five **Regional Internet Registries (RIRs)**. These non-profit organizations are responsible for distributing and managing IP address space within their specific geographic regions. They ensure fair and efficient allocation based on community-developed policies.

The five RIRs are:

African Network Information Centre (AfriNIC): Administers IP addresses for the continent of Africa.
American Registry for Internet Numbers (ARIN): Administers IP addresses for Canada, the United States, and many Caribbean and North Atlantic islands.
Asia-Pacific Network Information Centre (APNIC): Administers IP addresses for Asia, Australia, New Zealand, and surrounding countries.
Latin America and Caribbean Network Information Centre (LACNIC): Administers IP addresses for Latin America and parts of the Caribbean.
Réseaux IP Européens Network Coordination Centre (RIPE NCC): Administers IP addresses for Europe, the Middle East, and parts of Central Asia.

Each RIR maintains a public WHOIS database where you can look up information about the resources they manage. Our tool attempts to query these sources to bring you the relevant details.

Please note: The level of detail available can vary depending on the RIR's policies and the specific IP address or domain queried. For domain names, WHOIS information often points to the domain registrar rather than the end-user directly.
