An IP address checker is a free network diagnostic utility that instantly detects your public IPv4 or IPv6 address and retrieves detailed IP geolocation data, ISP identification, Autonomous System Number (ASN) metadata, and timezone information. Use it to find your public IP address, verify VPN connections, run a reverse IP lookup, or check the location of any IP worldwide.
An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. Think of it as a digital mailing address — it tells websites, servers, and routers exactly where to send data back to your device. There are two versions of IP addresses in use today: IPv4 (Internet Protocol version 4), which uses a 32-bit format like 192.168.1.1 and supports approximately 4.3 billion unique addresses, and IPv6 (Internet Protocol version 6), which uses a 128-bit format like 2001:0db8:85a3::8a2e:0370:7334 and supports a virtually unlimited number of addresses to accommodate the growing number of internet-connected devices worldwide.
Your public IP address is assigned to you by your Internet Service Provider (ISP) using protocols like DHCP (Dynamic Host Configuration Protocol). Most residential connections receive a dynamic IP that changes periodically, while businesses often use static IPs that remain constant. Every time you visit a website, send an email, or stream a video, your IP address is transmitted to the receiving server — making it a critical piece of your digital footprint. Using our free IP checker, you can instantly discover what is my IP address, verify whether your VPN or proxy is properly masking your real location, perform an IP address lookup on any address in the world, and understand your network's exposure. Checking your IP regularly is essential for maintaining online privacy, troubleshooting network issues, and ensuring your security tools are functioning correctly.
When you use our IP checker to look up an address, the tool returns several important data points. Here's what each one means and why it matters:
America/New_York, Asia/Kolkata) associated with the IP's geographic location. Useful for logging, scheduling, and forensic timestamp analysis.Simply open this page — our IP checker automatically detects and displays your public IP address the moment the page loads. No manual input, clicks, or downloads are required. Your IPv4 or IPv6 address, ISP, approximate location, and ASN are shown instantly.
Yes. Enter any valid IPv4 or IPv6 address in the search field to perform a complete IP address lookup. The tool will return the geolocation (city, region, country), ISP, ASN, timezone, and approximate coordinates for that address, displayed on an interactive map.
Absolutely. To check if VPN is working, turn on your VPN, then visit or reload this page. If the displayed IP address and location match your VPN server's country (rather than your actual physical location), your VPN is functioning correctly and your real IP is hidden. If it still shows your real location, your VPN may be leaking DNS requests or WebRTC data.
An IP address reveals your approximate geographic location (city and region, not your exact street address), your Internet Service Provider (ISP), the Autonomous System Number (ASN) managing your network, and your timezone. It does not reveal your name, physical home address, phone number, or browsing history. However, combined with other data, it can be used to build a profile of your general location and internet activity.
IPv4 (Internet Protocol version 4) uses a 32-bit address format (e.g., 203.0.113.45) and supports approximately 4.3 billion unique addresses. Due to the explosive growth of internet-connected devices, IPv4 addresses are nearly exhausted globally. IPv6 (Internet Protocol version 6) uses a 128-bit address format (e.g., 2001:0db8:85a3::7334) and supports 340 undecillion (3.4 × 10³⁸) unique addresses — enough to assign a unique IP to every atom on Earth's surface. IPv6 also includes built-in security features (IPsec) and more efficient routing. Our IP checker supports both formats.
IP geolocation accuracy varies by connection type. For fixed-line broadband connections, city-level accuracy is typically 80-90% reliable. For mobile networks, accuracy drops because carriers route traffic through regional gateways that may be in a different city. VPN and proxy users will see the VPN server's location, not their own. Country-level accuracy is generally 99%+ for all connection types. Our tool uses premium geolocation databases that are updated regularly to maximize precision.
An ASN (Autonomous System Number) is a globally unique identifier assigned to a network operator — such as an ISP, university, or cloud hosting provider — by a Regional Internet Registry (RIR) like ARIN, RIPE NCC, or APNIC. Each ASN controls a block of IP addresses and uses the Border Gateway Protocol (BGP) to exchange routing information with other networks. Our IP ASN lookup shows you which organization manages the network block associated with any IP address, which is essential for cybersecurity threat intelligence, abuse reporting, and network diagnostics.
Yes. Performing an IP address lookup using publicly available geolocation databases is completely legal in all jurisdictions. IP addresses are considered publicly visible network metadata — every time you visit a website, your IP is logged in the server's access records. Looking up the geographic origin, ISP, or ASN of a public IP address is no different from checking a phone number's area code. However, using IP data to harass, stalk, or conduct unauthorized network intrusions is illegal and punishable by law.
Yes, to a limited extent. Websites can log your IP address to determine your approximate location, identify your ISP, and detect repeat visits. However, IP addresses alone are not sufficient for precise individual tracking — they typically identify a household or organization, not a specific person. Most sophisticated user tracking relies on browser cookies, fingerprinting, and advertising IDs rather than IP addresses alone. Using a VPN, Tor, or privacy-focused browser can significantly reduce IP-based tracking.
There are several effective ways to hide your real IP address: (1) Use a VPN (Virtual Private Network) — the most popular method, which routes your traffic through an encrypted tunnel to a server in another location. (2) Use the Tor Browser — which bounces your traffic through multiple volunteer-operated relays worldwide. (3) Use a proxy server — which acts as an intermediary between your device and the internet. (4) Use a mobile hotspot — which assigns a different IP from your cellular carrier. After enabling any of these, return to this IP checker to verify that your real IP is no longer visible.
