Best for: WorldIP
WorldIP is an IP intelligence API built on the company's own scanner fleet rather than on resold third-party data. It sweeps the full IPv4 space — all 4.3 billion addresses — on a sub-daily refresh and returns, for any address you ask about, the owning organisation, ASN number and name, country, region and city, the CIDR block it sits in, and both reverse and forward DNS, as clean JSON in under a second. The site claims more than 80,000 ASNs tracked and over 1.2 billion reverse-DNS records. What makes it unusually easy to adopt is that the base lookup needs no key and no signup at all: curl worldip.io/8.8.8.8 from any shell returns the record over plain HTTP, which means it can be dropped into a helpdesk, CRM or dashboard as a URL-substitution for an existing WHOIS endpoint without writing an integration. Beyond the descriptive layer sit the paid ones — ASN and organisation enrichment, /24 neighbour context, hosted-domain listings, and a threat layer that classifies residential, mobile and datacenter proxies, VPNs, Tor exits and botnet nodes, with a trust score and live BGP state. Around the API is a set of free browsing tools: a live BGP and RIR feed dashboard, MOAS conflict and RPKI-invalid trackers, first-seen prefix and withdrawal monitors, bogon leak detection, RIR ownership-transfer tracking, a WHOIS/RDAP lookup, a CIDR calculator and an IPv4 exhaustion tracker.
Ideal use cases:
- •Teams or individuals who need full ipv4 sweep on a sub-daily refresh from an owned scanner fleet
- •Teams or individuals who need keyless curl api — 1,000 lookups a day with no signup
- •Teams or individuals who need proxy, vpn, tor, datacenter and botnet classification with a trust score
- •Teams or individuals who need live bgp feeds: moas conflicts, rpki-invalid roas, withdrawals, as-path deviations
- •Anyone focused on ip-intelligence workflows
- •Anyone focused on api workflows
