What's My IP
Find your public IP address with geolocation, ISP, timezone info. Check IPv4/IPv6 address, hostname, browser details. Free online IP lookup tool
Asking "what is my IP" sounds like one question but is actually four: my IPv4 (which Cloudflare and most websites see), my IPv6 (which some sites see and some IPv6-only services require), my IP behind NAT (different from what the world sees if you are on a home router), and my IP through VPN (different from your "real" IP). This page shows all of them, plus the typical reverse-DNS, ISP, approximate geolocation, and browser-level network info so you can answer the version of the question your actual problem needs.
IP types and what each tells you
- Public IPv4 — what websites see. Assigned by your ISP. Changes occasionally (residential) or stays fixed (business with static IP).
- Public IPv6 — newer. If your ISP provides IPv6 (most do in 2026), every device on your network has its own globally routable IPv6 address. Privacy extensions rotate these regularly.
- Private (LAN) IP — your device on your home/office network. 192.168.x.x or 10.x.x.x or 172.16-31.x.x. Not visible to the internet.
- NAT — the router gives all internal devices the same public IP. From inside, every device thinks its IP is its private one; from outside, all share the router's public IP.
- Through VPN — if you are connected to a VPN, websites see the VPN provider's IP, not yours. "What is my IP" tools show what websites see, which is the VPN endpoint.
Working example: what each value reveals
Input
Home user in Krakow, no VPN, Orange Poland ISP
Output
Public IPv4: 89.74.103.42 Reverse DNS: dynamic-pool-89-74-103-42.krk.orange.pl ISP: Orange Poland S.A. (ASN 5617) Geo: Kraków, Poland (~5 km accuracy from IP geolocation) Type: Residential dynamic Public IPv6: 2a02:a311:1c8a:9b00:abcd:1234:5678:9abc Subnet: 2a02:a311:1c8a:9b00::/64 (your /64 prefix) Type: Residential, privacy extensions ON (this address rotates) Local IP (LAN): 192.168.1.142 Router: 192.168.1.1 Network: 192.168.1.0/24 (your home subnet) The public IP is shared by every device on your home network via NAT. The IPv6 is per-device with privacy extensions rotating it every few days.
Geolocation from IP is approximate. ASN-level (your ISP, country) is accurate; city-level is right ~60-80% of the time; specific street address is impossible from IP alone — IP geolocation databases at best resolve to a metro area.
What people actually want when they ask
- "Verify my VPN is working" — public IP shown matches the VPN provider's region, not your real region.
- "Whitelist my IP at a service" — give them the public IPv4 (most firewalls use IPv4 ACLs). For business connectivity, you typically need a static IP from your ISP.
- "Configure port forwarding" — public IPv4 to forward TO; LAN IP of the target device on your network.
- "Block this person on my server" — the public IP they connect from. Be careful: NAT means hundreds of users can share one IP.
- "Detect what country someone is in" — IP-based geolocation. Useful for compliance, not for individual targeting.
- "DNS troubleshooting" — DNS server IP (often configured at the OS level), not your own IP.
IPv6 in 2026
IPv4 has ~4.3 billion addresses; ran out in 2011. ISPs use CGNAT (carrier-grade NAT) to share IPv4 across customers. IPv6 has 2^128 addresses; effectively unlimited. By 2026, ~55% of global traffic is over IPv6 (Google statistics).
For most users, IPv6 is invisible. Devices get IPv6 alongside IPv4 (dual-stack). When both are available, applications usually prefer IPv6. Some services are IPv6-only (newer ones launched after exhaustion); some are IPv4-only (older infrastructure). The IPv6 you see in this tool is your specific device; your spouse's phone on the same Wi-Fi has a different one (unlike IPv4 NAT).
When to reach for this tool
- You connected to a VPN and want to confirm your traffic appears from the new location, not your home.
- A service asked you to "tell us your IP for whitelisting" and you need both IPv4 and IPv6.
- You are troubleshooting "my internet works but the website does not load" and want to verify your IP and DNS resolution.
- You are travelling and want to verify which country your IP geolocates to (some services restrict by country).
What this tool will not do
- It will not show "your IP" inside a corporate VPN unless the VPN routes web traffic through. Split-tunnel VPNs route only internal traffic; web traffic still goes via your home/public IP.
- It will not detect every proxy. Some advanced proxy chains (Tor, multi-hop VPNs) show the final exit; the actual real IP is hidden by design.
- It will not give street-level location. IP geolocation databases (MaxMind, IP2Location) buy from ISPs and refine with ground-truth feedback. Accuracy is metro-area at best; "your IP is at 123 Main St" is fiction.
IP detection runs in your browser. The tool fetches the public IP from a public IP-detection endpoint (which sees the IP regardless); no additional information is logged or sent.
Frequently asked questions
Why does my IP keep changing?
Residential ISPs assign dynamic IPs from a pool. Restart your router and you may get a new IP. Some ISPs rotate IPs every few days or weeks; others keep the same IP for months. To get a fixed IP, either upgrade to a business plan or use a VPN with a static endpoint.
Can someone find my home address from my IP?
No — not without ISP cooperation or a legal order. ISP records map IP-at-time to a customer; that mapping is held by the ISP. Public databases give metro-area accuracy at best. Apps that claim "we know exactly where you are" do so through GPS/Wi-Fi triangulation (browser permission required), not IP.
What is the difference between public and private IP?
Public: globally routable; assigned by ISPs; visible on the internet. Private (RFC 1918 ranges 10.x, 172.16-31.x, 192.168.x): only valid inside your local network. Routers translate between the two via NAT.
Why are my IPv4 and IPv6 different?
They are independent address spaces. Your device has both — a private IPv4 (NAT'd to share the public IPv4) and a global IPv6 (each device gets its own). Websites use whichever the connection prefers (usually IPv6 if available).
Is my IP a security risk?
Knowing someone's IP alone enables: connection from that IP, geolocation to metro, ASN/ISP identification. It does NOT enable hacking into their device — that requires open ports + exploits. Standard home routers do not expose services to the internet by default. IP doxxing is a privacy concern (location), not a hacking concern.
How do websites know my IP if I am behind NAT?
Your router translates outbound connections to its public IP. The website sees the router's IP. Multiple devices behind the same router all appear as the same IP from the website's perspective. The router uses ports to track which device gets each response (Network Address and Port Translation, NAPT).
