What is my IP address?

Your IP address is a unique number that identifies your device on the internet. ipnow detects and displays your public IPv4 and IPv6 address at the top of this page automatically.

How do I find my IP address?

The fastest way to find your IP address is to open ipnow.dev — your public IP is shown instantly. No app, sign up or technical knowledge required.

What is the difference between IPv4 and IPv6?

IPv4 is the older 32-bit address format (e.g. 99.33.79.49). IPv6 is the newer 128-bit format that provides many more addresses. Many devices now have both.

Do I have both IPv4 and IPv6?

Many modern connections are "dual stack" and support both. Your IPv4 and IPv6 addresses are shown above when available. If only one appears, your network currently supports only that protocol.

Is IPv6 faster than IPv4?

Not inherently, but IPv6 can be more efficient by removing NAT overhead and simplifying routing. Real-world speed differences are usually small and depend more on your ISP and the destination server.

Why is IPv6 adoption taking so long?

IPv4 and IPv6 are not directly interoperable, so the transition requires upgrades across ISPs, hardware, and software. NAT extended IPv4's life, reducing urgency. Adoption is steadily growing but incremental.

Should I disable IPv6?

Usually no — IPv6 is the future of the internet and works fine for most users. The main exception is if a VPN only supports IPv4, in which case disabling IPv6 prevents leaks. Otherwise, leave it enabled.

IPv4 vs IPv6

IPv4 vs IPv6: the key differences

A clear side-by-side of the two IP formats — size, capacity, notation, and why the internet is moving to IPv6.

Size and capacity

IPv4 uses 32-bit addresses, allowing about 4.3 billion unique addresses — a supply exhausted globally around 2011. IPv6 uses 128-bit addresses, providing roughly 340 undecillion (3.4 × 10^38) addresses — effectively unlimited for the foreseeable future.

Notation

IPv4 is written as four decimal numbers separated by dots: 99.33.79.49. IPv6 is written as eight groups of four hexadecimal digits separated by colons: 2001:0db8:85a3::8a2e:0370:7334, with consecutive zero groups compressed to ::.

How they coexist

Most networks today run "dual stack", supporting both protocols simultaneously. Devices prefer IPv6 when a destination supports it, falling back to IPv4 otherwise. Transition technologies like NAT64 and 6to4 help IPv6-only and IPv4-only systems communicate.

Practical differences

IPv6 removes the need for NAT (every device can have a public address), has built-in support for IPsec, and simplifies routing. For privacy, IPv6 privacy extensions randomize your address over time — important because IPv6 addresses can otherwise be more uniquely identifying than shared IPv4.

IPv4, IPv6, and your privacy

What each format means for how identifiable you are online.

Identifiability differs

IPv4 users often share one public IP via NAT, making individuals harder to single out. IPv6 can assign a unique address per device, which is potentially more identifying — which is why privacy extensions exist to rotate the address.

We never log it

ipnow shows no ads and runs no trackers. We never store or log your IP address on our servers. Geolocation and ISP details are fetched from privacy-respecting third-party providers.

Avoiding IPv6 leaks

If you use a VPN, make sure it tunnels both IPv4 and IPv6. Many VPNs only handle IPv4, causing an IPv6 leak that exposes your real address. Reload this page while connected to your VPN to confirm both addresses show VPN values.

Frequently asked questions

Common questions about IP addresses and how ipnow works.

IPv4 uses 32-bit addresses (e.g. 99.33.79.49) with ~4.3 billion total. IPv6 uses 128-bit addresses (e.g. 2001:db8::1) with virtually unlimited capacity. IPv6 was created because IPv4 addresses ran out globally.
