Reverse IP
Reverse IP Lookup - Resolve IP to Hostname
Perform a reverse DNS lookup to find the hostname associated with an IP address.
How It Works
The tool queries PTR records in the DNS system. For IPv4, it queries the in-addr.arpa zone; for IPv6, the ip6.arpa zone.
Understanding Results
Results show the hostname(s) mapped to the IP. Not all IPs have reverse DNS configured. Multiple hostnames may indicate shared hosting.
