What is Reverse IP Lookup?
Reverse IP Lookup (also called Reverse DNS Hosting Lookup) lets you discover which domains are hosted on a given IP address. This is useful for security research, finding related sites on shared hosting, and identifying whether suspicious IPs are serving multiple domains. Enter any public IPv4 or IPv6 address to see all domains currently pointing to that IP.
