Bulk search for all domains resolved to an IP address to get a list of websites on the same server and their DNS resolution history.
When you detect suspicious traffic from a specific IP or want to investigate server hosting details, our Reverse IP Lookup tool can instantly retrieve all domains that have resolved to that IP. By querying DNS history, it outputs structured data including domain names and their first/last resolution times, helping you identify associated sites on the same IP. A single IP address can host multiple domains, which is a common occurrence with shared hosting and CDN networks.
Q: Why do some IP queries return empty results?
Possible reasons: 1) The IP has never had a domain resolved to it. 2) It is a reserved intranet address. 3) Our data sources have not yet indexed it.
Q: How can I tell if a domain in the results is still in use?
Check the LastDate field: If it hasn't been updated in over 3 months, the domain may have migrated. However, CDN node IPs can remain unchanged for long periods.
1) IPv6 address queries are not supported. 2) Enterprise users are advised to use our API for real-time data. 3) Results are for reference only; actual business decisions should incorporate additional information such as WHOIS data.
Typical use case: Security teams frequently use this tool to investigate phishing domains associated with malicious IPs. For example, entering 8.8.8.8 might return domains like google.com, but actual results will vary significantly based on CDN configurations. We recommend focusing on recently resolved domains (records with a recent LastDate), as these active associations are more worthy of attention.
