IP Intelligence Lookup
Returns reverse DNS (PTR) records, ASN/network ownership details, and a bogon/private-range flag for an IPv4 or IPv6 address.
If the ip parameter is omitted, the API falls back to the caller's own IP. For private, reserved, or non-routable addresses, is_bogon is true and the network fields are null. The response is best-effort: an address with no PTR record simply returns an empty reverse_dns array rather than an error.
query Parameters
ipThe IPv4 or IPv6 address to look up. If omitted, the caller's own IP is used.
