About IP WHOIS - Check Who Owns an IP Address

IP WHOIS Lookup Tool offers a free IP Lookup Service to check who owns an IP address. Just enter an IP and perform the IP Lookup to find which organization or individual owns that specific IP address.

IP WHOIS Lookup Tool

Go for Lookup IP WHOIS information using the IP WHOIS Lookup tool for any allocated IP address.

Every IP address that floats on the global public internet is administrated by one of the five RIRs, each working within a specific region of the globe. The RIRs and their regulatory areas are as follows.

African Network Information Centre (AfriNIC) Manages IP addresses for the Africa continent. https://www.afrinic.net/

American Registry for Internet Numbers (ARIN) Manages IP addresses for the United States, Canada, and many Caribbean and North Atlantic islands. https://www.arin.net/

Asia-Pacific Network Information Centre (APNIC) Manages IP addresses for Asia, Australia, and surrounding Countries. https://www.apnic.net/

Latin America and Caribbean Network Information Centre (LACNIC) Manages IP addresses for Latin America and the Caribbean. https://www.lacnic.net/

Réseaux IP Européens Network Coordination Centre (RIPE NCC) Manages IP addresses for Europe, the Middle East, and the former USSR. https://www.ripe.net/

IP WHOIS Lookup

Lookup IP WHOIS information using the IP WHOIS Lookup tool for any allocated IP address. This tool will provide you with the IP Address owners contact information. The results will also show the Regional Internet Registry (RIR) who assigns the IP, the assigned owner, location, contact information, and abuse reporting details. Other important information includes how many IP Addresses are in the block or blocks assigned to the owner of the IP you're researching.

IP WHOIS Results

You will get the information you should contact to reach out to the IP address owner from the IP WHOIS results. You will most likely get the Internet Service Provider (ISP) information to whom the IP address is assigned. If someone tries to spam or hack you, etc., it's best to dig out the abuse information included in the results. Otherwise, using the non-abuse contact information will be your best option when attempting to reach the controlling party.
