What the Internet Sees When You Connect
Every website you visit knows your public IP address. It’s how HTTP responses find their way back to your browser through the maze of routers between you and the server. Your ISP assigns it, and it’s visible to every service you connect to.
You’d be surprised how often you need to know your own IP. Setting up SSH access to a server and need to whitelist your IP in the security group? Configuring a VPN and want to verify it’s actually working? Troubleshooting why your home server isn’t reachable from outside? Step one is always: what’s my public IP right now?
Click the button. Get your IP. Copy it.
The Scenarios That Bring You Here
Firewall whitelisting. You’re deploying to a cloud server and need to restrict SSH access to your IP. Grab your current public IP, add it to the security group’s inbound rules, and connect.
VPN verification. You turned on your VPN. Did it actually work? Check your IP before and after connecting. If the IP changed to the VPN provider’s address, it’s working. If it’s still your home IP, something’s wrong with the VPN connection.
NAT debugging. You’re behind two levels of NAT — your home router and your ISP’s carrier-grade NAT. The IP you see in your router’s admin page isn’t necessarily the IP the outside world sees. This tool shows the actual public-facing address.
Dynamic DNS management. You’re running a home server with a dynamic IP. When your ISP changes your IP (which can happen on router restart or DHCP lease expiry), you need to update your dynamic DNS record.
Remote desktop setup. A coworker needs to connect to your machine remotely. They need your public IP. Look it up here, send it over, and configure the connection.
About Your IP Address
Most home connections use dynamic IPs that change periodically. Business connections typically have static IPs that stay constant. The tool shows whichever address your browser uses to connect — usually IPv4, but IPv6 if your network prefers it.
Your IP isn’t logged or stored. The detection uses a lightweight API call from your browser, and that’s it.
For detailed information about any IP address (geolocation, ISP, AS number), use the IP Address Lookup. To convert IPv4 addresses to their IPv6 equivalents, the IPv4 to IPv6 Converter handles the math.
