What Is My IP Address? Check Instantly

Free IP Address Lookup Tool

IPLookup is a free, privacy-first IP address lookup tool. When you visit our IP lookup page, we automatically detect your public IP address and show you detailed information about your internet connection — including your approximate location, ISP, ASN, timezone, and more.

Unlike many IP lookup websites, we do not store your IP address, use tracking scripts, or set cookies. All data is fetched in real time from public APIs and displayed instantly in your browser.

Whether you need to check your IP for troubleshooting, verify your VPN is working, or simply learn more about how the internet works, IPLookup provides accurate, real-time information with a clean, distraction-free interface.

What Is an IP Address?

An IP address (Internet Protocol address) is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies every device connected to the internet. Think of it as a digital mailing address — it tells other devices where to send data so you can browse websites, stream videos, send emails, and use online services.

Every time you visit a website, your device shares its IP address with the server hosting that site. This allows the server to send the requested data back to you. Without IP addresses, the internet as we know it would not function.

Your public IP address is assigned by your internet service provider (ISP) and is unique across the entire internet. Most residential connections use dynamic IP addresses that change periodically, while business connections often use static IP addresses that remain the same. Visit our what is my IP address page to learn more.

IPv4 vs IPv6

The internet uses two types of IP addresses: IPv4 and IPv6. IPv4 uses 32-bit addresses written as four numbers separated by dots (e.g., 192.168.1.1) and supports about 4.3 billion addresses. Because the world has run out of IPv4 addresses, IPv6 was developed. IPv6 uses 128-bit addresses written as eight groups of hexadecimal characters (e.g., 2001:db8::1) and supports a virtually unlimited number of addresses.

Most modern devices and ISPs support both protocols. IPLookup checks both your IPv4 and IPv6 addresses simultaneously and displays whichever is active. For a detailed comparison, see our IPv4 vs IPv6 guide.

Public vs Private IP Address

There is a critical distinction between public and private IP addresses. Your public IP address is what the rest of the internet sees — it is assigned by your ISP and is unique worldwide. Your private IP address is used only within your home or office network. Devices like your computer, phone, printer, and smart TV each receive a private IP from your router.

Private IP addresses fall into reserved ranges such as 192.168.x.x, 10.x.x.x, and 172.16.x.x. When you check your IP on IPLookup, you see your public IP address — the one visible to websites and online services.

How Accurate Is IP Geolocation?

IP geolocation estimates the physical location of an IP address based on ISP registration data. Accuracy varies: in urban areas it may place you within a few miles, while in rural areas it can be off by hundreds of miles. IP geolocation is not GPS — it cannot provide street-level accuracy or your exact physical address.

IP geolocation databases are maintained by companies that aggregate data from ISPs, regional internet registries, and user-contributed corrections. The accuracy depends on how frequently the ISP updates its records and how precisely the database maps IP ranges to locations.

Common uses of IP geolocation include content localization (showing region-relevant content), fraud detection (flagging transactions from unexpected locations), and network troubleshooting. When you use our IP lookup tool, the location shown is the ISP-registered location, not your precise physical address.

Can Someone Track Me With My IP Address?

Your IP address can reveal your approximate geographic location (usually at the city level) and your ISP, but it cannot reveal your name, home address, phone number, or personal identity. Websites you visit can see your IP address — that is how they send data back to you — but they cannot determine who you are from your IP alone.

Law enforcement can request ISPs to reveal customer information associated with an IP address, but this requires a legal process such as a subpoena or court order. For everyday browsing, your IP address primarily reveals your general location and which company provides your internet service.

If privacy is a concern, you can hide your IP address using a VPN, proxy server, or the Tor network. A VPN routes your traffic through a remote server, replacing your real IP with the VPN server's IP. Use our VPN detection tool to verify whether your connection is hiding your IP correctly. See our how to hide your IP address guide for detailed methods.

DNS Lookup and IP Comparison Tools

Beyond basic IP address lookup, IPLookup offers a suite of networking tools to help you diagnose and understand your internet connection:

• DNS Lookup — Query DNS records for any domain name. Supports A, AAAA, CNAME, MX, NS, TXT, SOA, and SRV record types via Cloudflare's DNS-over-HTTPS API. No authentication required.
• IP Comparison — Compare two IP addresses side by side to see their locations, ISPs, ASNs, and other details. Useful for verifying VPN connections or comparing network paths.
• Bulk IP Lookup — Look up multiple IP addresses at once with a progress bar. Process up to dozens of IPs simultaneously with a concurrency limit of 5 to avoid rate limiting.

Privacy-First IP Lookup

IPLookup is built with privacy as a core principle. Unlike many IP lookup websites that track visitors, serve invasive ads, or store query histories, IPLookup is designed to be completely transparent:

• No data storage — We do not store your IP address, lookup history, or any personal information on our servers.
• No tracking cookies — We do not use tracking scripts, fingerprinting, or third-party analytics that identify individual users.
• Browser-local only — Any data you see stays in your browser session. We use no databases and maintain no logs.
• Real-time API calls — IP data is fetched live from public APIs (ipinfo.io and ipify.org) when you visit the page. Nothing is cached or logged server-side.

Frequently Asked Questions About IP Addresses

What is my IP address?

Your IP address is the unique identifier assigned to your internet connection by your ISP. To see your current IP address instantly with detailed location and ISP information, visit our IP lookup page.

How do I find my IP address on my phone?

Visit IPLookup in your mobile browser — it works on both iPhone and Android. Your public IP address will be displayed instantly along with your location and ISP. You can also check your private IP in your Wi-Fi settings.

Why does my IP address keep changing?

Most ISPs assign dynamic IP addresses to residential customers. Your IP can change when you restart your router, after a lease timeout, or when your ISP reallocates addresses. Some business plans offer static IPs that never change. See our FAQ page for more details.

Does a VPN change my IP address?

Yes — a VPN replaces your real IP address with the VPN server's IP address. This makes it appear as though you are browsing from the VPN server's location. Use our VPN checker to verify your VPN is working correctly.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (e.g., 192.168.1.1) and supports ~4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) with virtually unlimited addresses. IPv6 was created because IPv4 addresses have been exhausted. Read our IPv4 vs IPv6 comparison for a full breakdown.
