IP Address Lookup
Your IPv4 and IPv6 address, shown instantly — no click required. Real geolocation, ASN, and an honest hosting/VPN signal, never a fabricated score. Free, no signup, no ads.
Your IP address
Detecting…Both checked independently — most connections only have one, some (dual-stack) have both. "Not detected on this connection" is a real, honest result, not an error.
Look up any IP or hostname
Check geolocation, ASN, and the hosting/VPN signal for any public IPv4, IPv6 address, or domain.
Geolocation data: geojs.io (free, no API key). Prefer JSON?
Call /api/my-ip.php (your IP) or /api/my-ip.php?ip=8.8.8.8 (any IP/host) directly — same data this page uses.
FAQ
What is my IP address?
It's shown above automatically the moment this page loads — no button click needed. We detect it server-side (a browser can't see its own public IP directly) and show your IPv4 address, your IPv6 address if your connection has one, or both.
IPv4 vs IPv6 — what's the difference, and why do I see both?
IPv4 addresses (e.g. 203.0.113.5) are the older, shorter format the internet has mostly run on since the 1980s — there are only about 4.3 billion of them, and they've effectively run out, which is why most home connections now share one via NAT. IPv6 (e.g. 2001:4860:4860::8888) is the newer, much larger address space designed to give every device its own globally unique address. Many networks are dual-stack — they have both — so this tool checks for each independently rather than assuming you only have one.
Why does my IP show a different city than I'm actually in?
IP geolocation is based on where your ISP or network operator has registered that IP block, not GPS or device location — it's genuinely just an estimate, and it's common for it to resolve to your ISP's regional hub, your mobile carrier's gateway city, or a completely different city if you're on a VPN, corporate network, or certain mobile/satellite connections. We label every location result 'approximate, ISP-based' for exactly this reason — never claim it as precise.
Can a VPN hide my IP address?
Yes — when you connect through a VPN, the sites you visit (including this one) see the VPN server's IP, not your real one. That's also why this tool flags addresses that belong to known hosting/cloud/VPN-provider networks: if you look up an IP and see a 'hosting/datacenter' flag, it's often (not always) a VPN, proxy, or cloud server rather than a home internet connection.
How does the hosting/datacenter detection work — is it a real VPN detector?
No, and we're upfront about that. Real-time VPN/proxy-detection databases are a paid product we don't subscribe to, so we won't pretend to offer one. Instead we check the IP's registered ASN and organization name against a curated list of well-known cloud and hosting providers (AWS, Google Cloud, Microsoft Azure, DigitalOcean, OVH, Hetzner, Cloudflare, and more). A match is a genuinely useful, honest signal — datacenter IPs are disproportionately VPNs, proxies, and servers — but it's a heuristic, not a verified yes/no, and we never show a fake confidence score.
Do you store the IP addresses I look up?
No. Each lookup is a live, real-time query — nothing you look up (your own IP or any address you enter) is logged to a database or shared with anyone. Requests are rate-limited purely to keep the free geolocation data source available for everyone.
Is there a raw API I can call directly?
Yes — this tool's own backend is a small, free, read-only JSON endpoint: GET /api/my-ip.php returns your own detected IP and network info, and GET /api/my-ip.php?ip=8.8.8.8 looks up any public IP or hostname. No key, no signup — the same endpoint this page itself calls.
