IPFerret shows your public IPv4 / IPv6, ISP, ASN, approximate location, and request fingerprint — fast, privacy-first, with one-tap copy and share. No logs. No tracking. No nonsense.
216.73.217.104ISP: Amazon.com, Inc.
Edge-cached, server-rendered.
No third-party tags, ever.
IP, DNS, WHOIS, CIDR, IPv6, headers, OUI…
No logs. No profiling. Open API.
Your connection
Every server you hit can see roughly this much about your connection. Finn surfaces it all in one place.
216.73.217.104IPv4Map is rendered server-side from a built-in landmask — no Google Maps, no third-party request, no JavaScript required. Geolocation is approximate; your public IP itself is exact.
Toolkit
A growing collection of free, privacy-first network tools — built into one cohesive product.
See your public IPv4/IPv6 along with ASN, ISP, country, and one-tap copy/share.
Resolve any host over DNS-over-HTTPS. Privacy-first, no logging.
Network, broadcast, mask, host count — IPv4 and IPv6.
Expand, compress, validate, and explore IPv6 addresses.
Cross-RIR registration data for any IPv4/IPv6 address.
What your browser actually sends — User-Agent, Accept, Sec-CH-UA, more.
Resolve a MAC address prefix to its hardware vendor.
Plain-English definitions — ASN, BGP, CGNAT, RDAP, more.
Long-form pieces that demystify how the modern internet works.
Privacy-first
IPFerret doesn't fingerprint your browser, doesn't store your IP in a database, and doesn't sell data to brokers. Display ads from Google AdSense fund the site — and EU/UK/Swiss visitors get an explicit 'do not consent' option through Google's CMP.
Built for speed
The IP, ASN, and geo data render before the browser parses a single byte of script. Subsequent interactions stream over the wire in milliseconds.
Developer-friendly
Every UI surface is backed by a small, documented JSON API. Hit the endpoints from curl, jq, a CI job, or a serverless function.

Short answers to the questions every visitor has when they land on an IP-lookup page.
Your public IP is the address the rest of the internet sees when your device sends traffic. It identifies your network, not you personally. Every site, API, and service you connect to receives it as the return label on your packets.
No — it's an estimate based on what your ISP registered against the address block. City-level accuracy is common, but it can be off by hundreds of miles, especially on mobile networks. Your public IP itself is exact.
Servers use it to route responses back to you, apply rate limits, geo-restrict content, and detect abuse. Your IP doesn't reveal your name or browsing history — but ISPs and law enforcement can correlate it with subscriber records.
A VPN routes your traffic through another server, hiding your real IP from sites you visit. Tor adds stronger anonymity but is slower. Restarting your router sometimes assigns a new dynamic IP from your ISP.
Developer API
Every route on this site is JSON-addressable. Wire it into a deploy script, a monitoring job, or a Slack bot in under a minute.
