About IP to Hostname

A hostname lookup (also known as a reverse DNS or rDNS lookup) converts an IP address to its associated hostname. This is the opposite of the more common ‘forward DNS lookup’ that converts a hostname to an IP address.

About reverse DNS lookups

  • Not all IP addresses have an associated hostname
  • The lookup relies on PTR (Pointer) records in the DNS system
  • Results may differ depending on the DNS servers used for the lookup
  • IPv4 and IPv6 addresses are both supported

About the IP to Hostname, IP Reverse DNS Lookup Tool
