What Is My IP Address?

A public IP address is the address an internet provider assigns to a connection, and it is the address every website, mail server and online service sees when that connection reaches them. DNSX reports your current public IPv4 and IPv6 addresses with your ISP, its Autonomous System Number, an approximate city-level location, and whether the connection comes from a known hosting or VPN network.

What is my IP address, and who can see it?

Every server you contact necessarily sees your public IP address, because it is the return address your packets are answered to. What that address reveals to them is your ISP and an approximate location, not your name, your street address or your identity.

DNSX sets no tracking cookies, keeps no lookup history tied to a visitor, and does not sell or share the result. The lookup is processed live and the answer is shown only to you.

What is the difference between my public and private IP address?

A public IP address is assigned by your ISP, is routable on the internet, and is shared by every device behind your router. A private IP address comes from a reserved range (10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16), is assigned by your router, and is never routed on the public internet. This page shows the public address.

How do I tell if my VPN is actually working?

A working VPN replaces the address the internet sees with one belonging to the VPN provider. If this page reports your VPN provider's organization and Autonomous System Number, and a location matching the server you selected, your traffic is being carried by the tunnel. If it still reports your home ISP's name, the VPN is not carrying it.

Check the IPv6 result as well as the IPv4 result. A common leak is a VPN that tunnels IPv4 only while the operating system continues to reach IPv6 destinations directly over the native connection, which exposes your real address to any dual-stack site.

What is CGNAT, and am I behind it?

Carrier-Grade NAT is an ISP sharing one public IPv4 address among many subscribers. If your router's WAN address falls inside 100.64.0.0/10 (the shared address space RFC 6598 reserves for this) but this page reports a different public address, your connection is behind CGNAT. A private WAN address such as 10.x.x.x on a modem in bridge mode is another common sign.

CGNAT is why inbound connections and port forwarding fail on some connections: the public address is not yours alone, so there is no port on it that the ISP can map back to your router. The usual remedies are requesting a static or dedicated IPv4 address from the ISP, or using IPv6, which is not subject to CGNAT.

What does my IP address reveal about me?

Approximate Location

Your IP is mapped to a city and region based on your ISP's network infrastructure. This is typically accurate to the city level for wired connections.

Internet Service Provider

The organization that assigned your IP address and provides your internet connection. Identified through ASN and RDAP registration data.

Connection Type

Whether your connection is residential broadband, mobile, or a hosting/datacenter IP. VPN and proxy connections are also detected.

IP Version

Whether you're connecting via IPv4 (like 203.0.113.1) or IPv6 (like 2001:db8::1). Many ISPs now support both protocols.

Frequently Asked Questions

What is my IP address?▼
Your IP (Internet Protocol) address is the unique numerical identifier assigned to your device by your Internet Service Provider (ISP). It's the address that websites and online services see when you connect to them. This page shows your current public IP address as seen by our server.
What is the difference between my public and private IP address?▼
Your public IP address is the one visible to the internet. Your ISP assigns it, and every device on your local network shares it. Your private IP address (like 192.168.x.x or 10.x.x.x) is used only within your home or office network and is not visible to websites. This tool shows your public IP address.
Why does my IP address show a different city than where I am?▼
IP geolocation maps your IP to the nearest data center or network hub operated by your ISP, not your exact physical location. It's common for your IP to be geolocated to a city 50-200 miles away, especially if you're in a suburban or rural area. Mobile connections and VPNs can show locations even further from your actual position.
Do I have an IPv4 and IPv6 address?▼
Most internet connections today have an IPv4 address. Some ISPs also assign an IPv6 address (a longer address with colons, like 2001:db8::1). If your ISP supports dual-stack, you'll have both. This tool detects and shows both your IPv4 and IPv6 addresses when available.
Can someone find my exact location from my IP address?▼
No. An IP address typically reveals your approximate location (city or region) and your ISP, but not your exact street address or identity. Only your ISP can map your IP to your physical address, and they are legally required to protect that information. Law enforcement can request this information with a court order.
How do I hide my IP address?▼
You can mask your IP address using a VPN (Virtual Private Network), which routes your traffic through a server in another location and shows that server's IP instead of yours. Other options include the Tor network (which routes traffic through multiple relays) or a proxy server. Our tool includes VPN, proxy, and Tor detection so you can verify if your IP is properly masked.
