IP to Hostname
Resolve an IP address back to a hostname.
When to use this tool
Reverse DNS lookup (IP to hostname) is used to identify the domain name associated with an IP address for security auditing and network analysis. It helps verify that an IP address belongs to the expected service or organization. Email servers often use reverse DNS to validate incoming mail sources and reduce spam.
How to use
Enter a valid IPv4 or IPv6 address in the input field. Click the "Resolve" button to perform a reverse DNS query. The associated hostname will appear in the output field once resolved.
