IP Checker

See your public IP, or look up any IPv4/IPv6 address — nothing leaves your browser except the address itself.

My IP

Detecting your address…

Detecting your IP calls ipify and ipwho.is directly from your browser — only your address is sent, no account, no other data.

IP Lookup

Looking up an address sends only that address to ipwho.is.

Check your IP address and look up any other

Free, no sign-up, no credit card, no trial. See your public IPv4/IPv6 address, ISP, ASN, and approximate location, or analyze any other address — nothing is ever uploaded or stored.

Your IP, instantly

See your public IPv4 and IPv6 address, ISP, and ASN the moment the page loads.

Look up any address

Enter any IPv4 or IPv6 address to see its ISP, ASN, and approximate location.

Public, private, or reserved

Instantly classifies private, loopback, link-local, and other special-use ranges — no network call needed.

Private by design

No account, no server round trip for your data — just the address sent to the lookup services.

Frequently asked questions

How does this tool find my IP address?
Your browser calls two free, key-less lookup services — ipify (for your IPv4 and IPv6 addresses) and ipwho.is (for ISP, ASN, and approximate location) — directly, with no server in between. Only your address is sent; nothing is uploaded or stored.
How accurate is the location shown?
IP-based geolocation is approximate — typically accurate to a city or region, sometimes only a country, and it can be outdated or simply wrong (especially on mobile networks, VPNs, and corporate connections). It's never your exact physical address, and this tool never claims otherwise.
Can I look up any IP address, not just my own?
Yes — enter any IPv4 or IPv6 address in the IP Lookup section. Private, loopback, and other special-use addresses (like 192.168.x.x or 127.0.0.1) are recognized instantly without a network call, since they have no public geolocation data.
What does "Network domain" mean, and is it a reverse DNS lookup?
It's the ISP or organization's registered domain (e.g. "comcast.net"), not a true reverse-DNS (PTR) hostname for that exact address — browsers can't perform a real PTR lookup. When ipwho.is has no domain on record, it shows as not available rather than a guess.
Why don't I see an IPv6 address?
Not every connection has IPv6 — if your network or ISP doesn't support it, only your IPv4 address will show. This is normal and doesn't affect the accuracy of your IPv4 details.
Is anything uploaded or stored on a server?
No. This tool runs entirely in your browser and has no backend of its own — it only calls the two named third-party services above to resolve IP data, and nothing you look up is saved.
