Get geolocation, ISP, and details for any IP
IP Lookup takes any public IPv4 or IPv6 address and returns what it can be geolocated to: approximate country, region, and city, the owning ISP or hosting provider, the Autonomous System (ASN) that announces the address, and the local timezone. It reads the results from public IP-geolocation and registry data rather than probing the device itself, so you get an instant snapshot without sending traffic to the target.
Network engineers use it to confirm where a server or client is hosted, security teams use it to triage suspicious IPs from logs, and developers use it to sanity-check the geo data behind rate limits, fraud rules, or CDN routing. Enter an address like 8.8.8.8 or 2001:4860:4860::8888 and read back the fields in seconds.
An IP address is not physically stamped with a location. Geolocation is inferred by mapping the address to data that IS known: which Regional Internet Registry (ARIN, RIPE, APNIC, LACNIC, AFRINIC) allocated the block, which organization owns it via WHOIS, which Autonomous System (ASN) announces it in BGP routing, and observed latency and infrastructure data collected by geolocation providers. These signals are combined into a best-guess city or region.
Because of this indirection, accuracy varies. Country-level results are usually reliable (often 95%+), but city-level results can be off by tens or hundreds of kilometers, and mobile, satellite, or corporate-VPN addresses frequently resolve to the provider's hub rather than the user. The coordinates returned are a centroid for the mapped area, not a precise device location.
The ASN is often the most trustworthy field. For example, 8.8.8.8 belongs to AS15169 (Google LLC) and 1.1.1.1 to AS13335 (Cloudflare). The ASN tells you who actually routes the address, which is why it is a strong signal for identifying hosting providers, VPN exits, and cloud regions even when the city guess is imperfect.
Yes, it is free to use with no signup. You only submit the IP address you want to look up; the tool does not store a personal history, and it queries the target only through public geolocation and registry data, not by contacting the device you enter.
Country-level accuracy is generally high, but city and coordinate accuracy is approximate and can be wrong by significant distances. Treat the location as a best estimate, not a precise GPS position, especially for mobile, VPN, or cloud IPs.
Yes. Leave the input empty (or enter your public IP) to see how your connection appears to external servers, including the ISP and region attributed to you.
Yes. The tool accepts both IPv4 dotted-quad addresses and full or compressed IPv6 addresses such as 2001:4860:4860::8888.
Geolocation reflects the exit IP, not you. When you use a VPN, proxy, or Tor, the address resolves to the provider's server location, which is exactly why these services change your apparent geography.
An Autonomous System Number identifies the network that announces the IP in BGP routing. It reliably tells you who operates the address (for example a specific cloud or hosting provider), often more dependably than the city guess.
No useful result will come back. Private ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and reserved addresses are not routable on the public internet and have no geolocation.
