WorldIP

Sub-second IP intelligence API — owner, ASN, geo, rDNS, live BGP and proxy/VPN detection

0
freemiumThe keyless public API is $0 forever and allows 1,000 lookups per day with no account, no API key and no TLS requirement — it returns IP, rDNS/PTR, forward DNS, ASN, org/owner, country, region, city and CIDR, and is explicitly positioned as a drop-in swap for a WHOIS URL endpoint in existing tools. A free account key is also $0 forever and lifts basic lookups to unlimited at roughly ten times the keyless volume. Paid tiers are metered monthly and add ASN and organisation enrichment, /24 neighbours, hosted domains, live BGP and the threat layer — residential, mobile and datacenter proxy detection, VPN, Tor and botnet classification, and trust scores. Full geolocation, DNS, ASN and org name are included on every plan including the free ones; the company's stated positioning is that the threat and enrichment layers cost a fraction of what incumbent providers charge.View full pricing →

About 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.

WorldIP Pros & Cons

✅ Pros

  • +No-key, no-signup base API is the lowest-friction integration in the category
  • +Owning the scanner means the data is first-party rather than resold
  • +Free BGP and RIR dashboards are useful even if you never call the API

⚠️ Cons

  • −Paid tier pricing is described as metered rather than published as fixed figures
  • −Keyless endpoint runs over plain HTTP, which not every environment will accept
  • −IPv4-focused — IPv6 coverage is not part of the headline claim
