IP Lookup retrieves RDAP registry data and reverse DNS for any IPv4, IPv6, domain, or URL. Private/reserved ranges short-circuit immediately and are never sent to an external provider.
Never. When you enter a URL, this tool only uses standard URL parsing to extract its hostname — it never makes a request to the URL itself.
Because those are private or reserved-range addresses (e.g. RFC 1918 private ranges, loopback) that are not publicly routable on the internet. This tool short-circuits them immediately and never sends them to any external lookup provider.
Yes. RDAP is routed through the official IANA bootstrap files to the correct regional registry (ARIN, RIPE NCC, APNIC, LACNIC, or AFRINIC) for a live query, and reverse DNS uses a standard DNS PTR lookup — both are real, free, keyless data sources.
