WHOIS and IP intelligence

WHOIS and IP address lookup

Find the registered owner, network allocation and published contacts for a domain or IP address.

Enter a domain or a public IPv4 or IPv6 address.

Why the zone date matters

The creation date in a WHOIS record is supplied by the registrar and can be absent, redacted, or simply wrong. We diff the ICANN zone files daily, so we also know the first day the registry itself published the domain's delegation. That date cannot be edited by whoever registered it.

It only covers domains delegated since our zone capture began, so it is shown as evidence when we have it and left out when we do not. We never estimate it.

Monitor new lookalikes of your company domain

Recurring domain checks attach available DNS, certificate, and registration evidence to potential matches.

Try monitoring one company domain for 14 days with a verified work email. One trial per company domain, no card required. Monitoring stops unless you subscribe; your saved assessment remains available.
