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 is the difference between internal and external IP?

Your external IP is your public, internet-facing address (shown above), assigned by your ISP. Your internal IP is your device's address within your local network. NAT on your router translates between them.

How do I find my internal IP address?

Windows: `ipconfig` in Command Prompt. Mac: System Settings → Network → Details. Linux: `ip addr` or `hostname -I`. Phones: Wi-Fi network details in Settings. Look for an address beginning with 192.168 or 10.

Can someone access my device using my internal IP?

Only devices on the same local network can reach your internal IP. Someone on the internet cannot connect to it directly unless you have set up port forwarding on your router that maps a public port to your internal IP.

What is my internal IP address?

The IP above is your external (public) IP. Your internal IP is the address used inside your own network — here is what "internal" means and how to find yours.

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

Internal vs external IP addresses

"Internal IP" is another name for your private/local address. Here is how it differs from your external IP and how to find it.

Internal IP = private/local IP

"Internal IP address" is another term for your private or local IP — the address that identifies your device inside your own network. It is called "internal" because it works only within the boundary of your LAN, as opposed to the "external" IP that faces the internet.

Internal vs external IP

Your external IP (shown above) is your internet-facing public address, assigned by your ISP and shared across your network. Your internal IP is assigned by your router to each device and is only visible inside your network. Traffic passes between the two through NAT on your router.

Internal IPs in business networks

In office and enterprise networks, "internal IP" often refers to addresses on the corporate LAN or VLAN. Internal services (file servers, intranets, printers) are reachable only from inside the network via these internal IPs, while external IPs handle internet traffic through firewalls and gateways.

How to find your internal IP

Windows: run `ipconfig` and read the IPv4 Address. macOS: System Settings → Network → your connection → Details. Linux: `ip addr` or `hostname -I`. Phones: check the connected Wi-Fi network details in Settings. It typically starts with 192.168 or 10.

Internal IP addresses and security

What your internal IP reveals inside your network versus what the internet sees.

Internal IPs stay inside your network

Your internal IP is not exposed to the internet — only your external (public) IP is. Websites and external services see the public IP shown above, never your internal 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.

When internal IPs matter for security

Internal IPs are used for network segmentation, firewall rules, and reaching internal services. Knowing your internal IP is essential for configuring port forwarding, static assignments, and internal DNS — all tasks that stay within your own network perimeter.

Frequently asked questions

Common questions about IP addresses and how ipnow works.

Your internal IP (e.g. 192.168.1.5) is the address your router assigns your device within your network — also called a private or local IP. It is not visible online, so read it from your device settings using the steps above. The IP shown at the top of this page is your external (public) IP.
