Finding Your Public IP Address
概要
Your public IP address is the identifier your network presents to the internet, used by websites and services to reach you. This tool shows the IP address your connection is currently using, which is handy for troubleshooting, remote access, and verifying a VPN.
使い方（ステップ）
- 1
Open the tool
Your public IP appears automatically.
- 2
Check VPN status
If you use a VPN, confirm the shown IP differs from your real one.
- 3
Copy if needed
Copy the address to share for remote-access or support purposes.
仕組み
When your browser requests a page, the server sees the public IP assigned by your internet provider (or your VPN, if active). The tool reports that address back to you. Note this is your network's public IP, not the private local IP your device uses inside your home or office network — those are different and serve different purposes.
こんなときに使う
Confirming a VPN is masking your real IP. Setting up remote access or port forwarding that needs your current IP. Giving your IP to a support agent for troubleshooting.
よくある質問
Your public IP is what the internet sees and is shared by your whole network; private IPs (like 192.168.x.x) identify individual devices inside your local network.
