Use IP WHOIS results

The WHOIS IP lookup tool is how you find out who an IP address belongs to. With IP WHOIS results, you will be able to find out exactly who to contact if you need to contact the owner of a certain IP address. You will also see information related to the Internet service provider (ISP) that has been assigned to the IP address. You can find similar information for your own IP on the What is My IP home page.

If you are a victim of IP abuse or IP spam, use the IP WHOIS results to contact your ISP and file a complaint. You can also use non-abusive contact information. However, you should contact your ISP first as the IP address owner may not actually be behind the abuse.
