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.

How do I find my router's IP for the admin page?

Your router's local admin IP is typically 192.168.0.1 or 192.168.1.1. On Windows, run `ipconfig` and look for Default Gateway. On macOS, go to System Settings → Network → your connection → Details.

What is the difference between public and local IP for port forwarding?

Your public IP (shown above) is what the internet connects to. Your local IP (192.168.x.x) is what your router forwards that traffic to. Port forwarding maps: public IP + port → local IP + port.

Why isn't my port forwarding working?

Common issues: (1) wrong local IP in the router rule (device IP may have changed), (2) the service isn't running, (3) Windows Firewall is blocking the port, (4) your ISP blocks that port (common for port 80/443 on residential plans), (5) your public IP changed.

Is port forwarding safe?

It depends on what's behind the port. Exposing a well-secured, updated service is relatively safe. Exposing an unpatched service is dangerous. Always keep the service updated, use strong credentials, and close ports you no longer need.

What is my IP address for port forwarding?

Q: 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.

Port forwarding requires your public IP so others can reach a specific device or service on your home network. It's shown above — copy it for your router settings.

IP addresses and port forwarding

How port forwarding uses your public IP, how to set it up, and how to handle dynamic IP changes.

What port forwarding does

Port forwarding tells your router to send incoming traffic on a specific port to a particular device inside your local network. External traffic arrives at your public IP (shown above) on a port, and the router forwards it to the right internal device.

How to set up port forwarding

Log into your router admin page (usually 192.168.0.1 or 192.168.1.1). Find Port Forwarding (sometimes called Virtual Server or NAT). Add a rule: external port, your device's local IP, and the internal port. The public IP shown above is what remote services use to reach you.

Static vs dynamic IP for port forwarding

Port forwarding rules on your router are permanent, but your public IP can change. When it does, any saved connection using the old IP breaks. Use a free DDNS service (No-IP, Duck DNS) to map a stable hostname to your ever-changing IP and keep connections working.

Security considerations

Every open port is a potential entry point to your home network. Only forward the ports you actively need, close ports when no longer in use, and make sure the service behind each port is kept up to date. Prefer non-default ports where possible to reduce automated scanning.

Port forwarding security and your IP

Understanding the risks of open ports and how to keep your network secure.

Who can reach your open ports

Once a port is forwarded, any machine on the internet can attempt to connect to your public IP on that port. Automated scanners find open ports within minutes. The service behind the port must be secure enough to withstand this exposure.

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.

Reducing your attack surface

Close ports that are no longer needed. Restrict access to specific trusted IP addresses in your router or firewall rules. Use non-default port numbers to reduce drive-by scanning. For sensitive services, require VPN authentication before the service is reachable.

Frequently asked questions

Common questions about IP addresses and how ipnow works.

When setting up port forwarding, your public IP (shown above) is the address external services connect to. In your router settings, you also need your device's local IP (192.168.x.x) as the destination to forward traffic to.
