IP lookup FAQ

What can I search with IP lookup?

You can search IPv4 addresses, IPv6 addresses, CIDR prefixes, ASNs, domains, hostnames, and MAC addresses.

Where does the lookup data come from?

Results are labeled with their source, such as RDAP, DNS, RPKI, IRR, curated OUI data, or fixture-backed BGP data where live sources are not enabled.

Does this page store my lookup?

The lookup pages are served with no-store cache headers. Aggregate server analytics use bounded feature labels rather than full lookup values.
