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 port does Windows Remote Desktop use?

Windows RDP uses TCP port 3389 by default. You must forward this port on your router to the target PC. For security, you can change it in the Windows registry (HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp → PortNumber).

How do I fix 'can't connect' to Remote Desktop from outside?

Check: (1) Remote Desktop is enabled on the target PC, (2) port 3389 is forwarded on your router to the PC's correct local IP, (3) Windows Firewall allows Remote Desktop, (4) you're using the correct public IP — get it from ipnow.dev on the host PC.

Can I use Remote Desktop if my IP changes every day?

Yes, with a dynamic DNS (DDNS) service. Sign up for a free hostname at No-IP or Duck DNS, install their update client on your PC, and connect to RDP using the hostname instead of the IP. The hostname always points to your current IP.

Is it safe to open port 3389 to the internet?

It carries significant risk — RDP is frequently targeted by brute-force and ransomware attacks. Safest approach: use a VPN (e.g. WireGuard) so RDP is only accessible inside a secure tunnel. Never expose RDP with a weak password.

What is my IP address for remote desktop?

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.

To remote into your PC from outside your home network, you need your public IP (shown above) and port 3389 forwarded through your router.

IP addresses and Remote Desktop (RDP)

How to use your public IP to set up remote desktop access, handle dynamic IPs, and secure your RDP connection.

Remote Desktop and your public IP

Windows Remote Desktop Protocol (RDP) lets you control a PC over the network. From outside your home, you connect using your public IP (shown above) plus port 3389. Your router must have port 3389 forwarded to the target PC's local IP address.

Setting up RDP access

Enable Remote Desktop on the target PC: Settings → System → Remote Desktop → Enable. Then log into your router admin page and forward TCP port 3389 to the PC's local IP. Find the PC's local IP by running `ipconfig` in Command Prompt and noting the IPv4 Address.

Solving the dynamic IP problem

Your public IP changes when your router restarts or your ISP reassigns it, breaking saved RDP connections. Fix this by requesting a static IP through your ISP (usually costs extra), or use a free DDNS service like No-IP that maps a stable hostname to your changing IP.

Securing your RDP access

Exposed RDP is one of the most attacked surfaces on the internet. Mitigate risks by: changing the default port (3389) to a non-standard one; enabling Network Level Authentication; restricting allowed IPs in Windows Firewall; or placing your PC behind a VPN so RDP is never directly internet-facing.

Is it safe to expose Remote Desktop to the internet?

RDP is powerful but carries significant security risks when exposed publicly. Here is what to know.

What RDP exposure means

Forwarding port 3389 to your PC makes it reachable from anywhere on the internet. Bots continuously scan for open RDP ports. A strong password and Network Level Authentication are the minimum — a VPN layer is strongly recommended.

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.

Best practices for secure RDP

Use a VPN (e.g. WireGuard or OpenVPN on your router) so RDP is only accessible through the VPN tunnel. Alternatively, use Tailscale or Microsoft Remote Desktop with Azure AD for a more managed, secure approach that avoids exposing port 3389 publicly.

Frequently asked questions

Common questions about IP addresses and how ipnow works.

Use the public IP shown at the top of this page, with port 3389. In Windows Remote Desktop Connection, enter `YOUR_PUBLIC_IP:3389`. Make sure port 3389 is forwarded on your router to the target PC's local IP.
