IPFerret is a privacy-first IP & network lookup product — public IP, ASN, DNS, WHOIS, CIDR, IPv6, headers — with a curious ferret mascot named Finn.

IPFerret is a modern, privacy-first reimagining of the IP lookup page. Instead of the dusty 2008-era one-pagers most network tools still ship, it bundles 13+ utilities — public IP, ASN explorer, DNS-over-HTTPS, WHOIS/RDAP, CIDR calculator, IPv6 toolkit, headers inspector, MAC vendor — into one cohesive product with dark mode, mobile apps, a documented JSON API, and a ferret named Finn. No third-party trackers beyond the disclosed AdSense loader, no fingerprinting, no data brokers.

IPFerret (ipferret.com) is a free, privacy-first network lookup tool led by Finn the IP Ferret. It surfaces your public IP, ISP/ASN, approximate geolocation, browser fingerprint, and request headers in milliseconds — server-rendered, no JavaScript required on first paint. Beyond the homepage it ships a growing toolkit: DNS-over-HTTPS, CIDR/subnet math, IPv6 expand/compress, WHOIS/RDAP across all five regional internet registries, MAC vendor lookup, glossary, and a dozen plain-English explainers on topics like CGNAT, BGP hijacking, and TLS. Every UI surface is JSON-addressable via /api/*. The site is self-hosted on a single Linux VPS, Open Graph cards are generated per route, and the source is intentionally documented for forks.
