Free IPv4 Lookup — Owner, ASN, Geo, PTR
Summary
WorldIP.io launches a free IPv4 lookup service that lets users search any address, CIDR range, ASN, organization, country, state, or city. The tool returns ownership, ASN, geolocation, reverse DNS, PTR records, and allocation history for IPv4 addresses. It also provides country, region, and city breakdowns of IPv4 allocation and lets users browse the full IPv4 space. The service combines MaxMind, RIR delegation files, and Team Cymru data, and it refreshes weekly.
