IP Address Lookup
Instantly look up any IP address — geolocation, ISP, ASN, timezone, and connection type. Your own IP is detected automatically.
What is an IP address?
An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a network. It serves two purposes: host identification (who you are) and location addressing (how to reach you). Every time your device communicates with a website or server, your public IP is visible to the destination.
The internet currently uses two versions simultaneously: IPv4 (e.g. 192.0.2.1) and IPv6 (e.g. 2001:0db8::1). IPv4 uses 32-bit addresses (about 4.3 billion possible) while IPv6 uses 128-bit addresses — enough for every grain of sand on Earth to have trillions of addresses.
Public vs. private IP addresses
Your public IP is the address your ISP assigns to your internet connection — it's visible to the outside world and is what this tool displays. Your private IP is the address your router assigns to each device on your local network (typically in ranges like 192.168.x.x or 10.x.x.x) — these are not directly visible from the internet.
Most home users share a single public IP across all their devices via NAT (Network Address Translation) in their router. On mobile networks, thousands of users may share the same IP.
What is an ASN?
An Autonomous System Number (ASN) is a unique identifier assigned to a network operator — typically an ISP, university, cloud provider, or large organisation. ASNs are the building blocks of internet routing: each AS announces which IP ranges it controls, and routers use this information to forward traffic globally. Cloudflare is AS13335, Google is AS15169, Amazon AWS is AS16509.
What does IP geolocation mean?
IP geolocation maps an IP address to a physical location based on registration data and routing information. Accuracy varies: country is usually correct, city is typically accurate to 25–50 km for broadband connections, and may be less accurate for mobile or VPN users. Geolocation works by cross-referencing IP range ownership records (WHOIS/ARIN/RIPE) with observed routing patterns.
Why does my IP show a different city?
Your public IP is registered to your ISP, and the location shown is usually your ISP's nearest network node, not your home. ISPs aggregate traffic from entire regions to single exchange points — so a user in a suburb may show as being in their nearest capital city. VPN users will show the VPN server's location, not their real one.
Static vs. dynamic IP addresses
A static IP never changes — useful for servers, remote access, and hosting. A dynamic IP is reassigned periodically by your ISP (often at each router restart). Most residential broadband connections use dynamic IPs from a shared pool. Business plans typically offer static IPs as an optional add-on.
