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.

IP WHOIS Results
With the IP WHOIS results, you'll be able to find out exactly who to contact should you need to reach out to the owner of the IP address. You'll most likely be shown the information of the Internet Service Provider (ISP) which has been assigned the IP. If someone is spamming you, attempting to hack you, etc. it's best to reach out to the abuse information contained in the results. Otherwise, using the non abuse contact information will be your best option when attempting to reach the controlling party.
Why is WHOIS uppercase?
WHOIS is pronounced as who is. Nothing too cryptic about that, right. The reason WHOIS is uppercase is because it's a query and response protocol that is used for querying databases that contain the registered users of IP addresses. The WHOIS protocol is also used to query other types of databases that contain similar information regarding domain names.
