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.

What are the private IP address ranges?

RFC 1918 defines them: 10.0.0.0–10.255.255.255, 172.16.0.0–172.31.255.255, and 192.168.0.0–192.168.255.255. Home networks usually use 192.168.x.x.

Can two networks have the same private IP?

Yes. Private IPs are not routable on the internet, so millions of networks can all use 192.168.1.1 without conflict. The address only has meaning inside each individual network.

Is my private IP visible to websites?

No. Websites see only your public IP. Your private IP stays within your local network. (Historically WebRTC could leak it in some browsers, but modern browsers block this.)

Which IP do I use for port forwarding?

Both: external traffic arrives at your public IP (shown above), and your router forwards it to the private IP of the target device. The forwarding rule maps public IP + port → private IP + port.

Public vs private IP address

The IP above is your public address — the one the internet sees. Below, learn exactly how it differs from your private IP and why you have both.

Your public IP address

216.73.216.157

IPv6Not available

This is the address that websites, apps and online services see when you connect. ipnow doesn't store or log it.

Network & ISP

Location is estimated from your IP address and may differ from your exact physical location.

Public vs private IP addresses

The clearest way to understand the two kinds of IP address every home network uses.

What a public IP is

A public IP address is assigned by your ISP and is unique across the entire internet. It is your network's single, internet-facing address — the one shown above — and every website you visit sees it. All devices in your home share this one public IP.

What a private IP is

A private IP address identifies a single device inside your local network. Drawn from reserved ranges (10.x.x.x, 172.16–31.x.x, 192.168.x.x), private IPs are not routable on the internet and can be reused by every network in the world without conflict.

How NAT connects them

Your router uses NAT (Network Address Translation) to bridge the two. When a device with a private IP requests the internet, the router swaps in the public IP, then routes replies back to the correct device. This lets many devices share one public address.

How to find each one

Your public IP is shown at the top of this page. Your private IP is read from your device: Windows `ipconfig`, Mac System Settings → Network → Details, Linux `ip addr`, or your phone's Wi-Fi network details. It will start with 192.168 or 10.

Which IP matters for your privacy?

Understanding which address is exposed and which stays hidden.

Only your public IP is exposed

Websites and online services see only your public IP, which can reveal your approximate location and ISP. Your private IP stays inside your network and is invisible to the internet, so it carries little privacy risk.

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.

How to mask your IP

Use a reputable VPN to replace your public IP with the VPN server's address, or the Tor network for stronger anonymity. On Apple devices, iCloud Private Relay (iCloud+) masks your IP in Safari. None of these change your local/private IP — only what the public internet sees.

Frequently asked questions

Common questions about IP addresses and how ipnow works.

A public IP is assigned by your ISP and visible to the whole internet (shown above), shared by all your devices. A private IP is assigned by your router and identifies a single device within your local network. NAT translates between them.
