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.
