IP Address Lookup
An IP address lookup shows who runs an IP address and roughly where it is: the ISP or organization, the ASN (network number), the reverse DNS name and an approximate, city-level location. Enter any IPv4 address, IPv6 address or domain below. Your own address is detected and shown instantly.
Free, no signup, no ads. Location is an estimate from registration data, not GPS, and we never show a made-up risk score.
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.
How to look up an IP address
- Find the address. It is the first thing on this page. For another device, check its network settings, or run
ipconfig(Windows) orifconfig/ip addr(macOS, Linux) for a local address. - Paste it into the lookup box. It accepts public IPv4, IPv6 and domain names. Private ranges such as 192.168.x.x have no public lookup.
- Read the result. The ISP/organization and ASN tell you who runs the network; reverse DNS often names the provider or host; the location is an estimate; the hosting flag tells you if the range belongs to a known cloud or datacenter provider.
- Share or go deeper. Copy the link to the result, or open the registry (RDAP) record for the registered owner of the address block.
What an IP lookup can and cannot tell you
- The ISP or organization behind the address
- The ASN and reverse DNS name
- Country and usually city, approximately
- Whether the range looks like cloud or datacenter hosting
- A person's name or street address
- A precise or GPS location
- Whether an address is a VPN, with certainty (we give a hosting-range signal only)
- Browsing history or activity

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.
How do I look up the IP address of a website or domain name?
Type the domain (for example example.com) into the lookup box above and we resolve it to its IP address, then show that address's ISP/organization, ASN and approximate location. You can also do it yourself: on Windows, macOS or Linux open a terminal or Command Prompt and run nslookup example.com (or dig example.com on macOS/Linux). A site behind a CDN such as Cloudflare will show the CDN's address, not the origin server's.
Can an IP address lookup tell me who someone is or their exact location?
No. A public lookup shows the network an address is registered to (the ISP or organization), the ASN, and an approximate location, usually city level and sometimes only country. It does not reveal a person's name, street address or device. For the registered owner of an address block, follow the 'Registry record (RDAP)' link on a result.
What is an ASN?
An ASN (Autonomous System Number) identifies a network that routes traffic on the internet, for example an ISP, a cloud provider or a large company. If you see AS15169 you are looking at Google's network. The ASN is often the most reliable part of a lookup because it comes from routing data rather than from a location estimate.
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.
