Reverse IP Lookup — sites on the same IP

Reverse IP Lookup shows a list of domains sharing the same IP address. This is useful for analyzing virtual hosting, investigating phishing, and researching infrastructure.

Use cases

• Virtual hosting — hundreds of websites can share a single IP;
• Security — neighboring sites can affect the IP's reputation;
• Competitive analysis — identify where competitors are hosted;
• Threat intelligence — discover related malicious domains on the same server.

Limitations

• The list covers only domains in the hackertarget.com index — the actual number of neighbors may be higher.
• Dedicated servers and CDNs (Cloudflare, Akamai) often have thousands of domains on one IP — results can be very large.
