Everything you need to know about Reverse IP lookup
Reverse IP lookup is a technique that finds all domains and websites hosted on a specific IP address. Unlike a forward DNS lookup (domain → IP), reverse IP lookup shows you all domains pointing to that IP.
Multiple domains can point to the same IP address through shared hosting, where many websites are hosted on the same server. Virtual hosting technology allows one server to host hundreds of domains.
If only one domain is found, the IP is likely a dedicated IP address used exclusively by that domain. This is common for large websites, SSL certificates, and email servers.
Accuracy depends on the data source. Our tool uses multiple DNS databases to provide comprehensive results. However, some domains may be missed if they use CDNs or have low DNS propagation.
Reverse IP shows all domains hosted on an IP address. WHOIS shows registration information about a specific domain (owner, registrar, dates). They serve different purposes but complement each other.
