CheckIP.ca

Find your IP address on any device

Start by deciding which address you need: the public address seen by websites, or the local address used inside your network.

Your public IP: any browser

Connect the device to the Wi-Fi, Ethernet, or mobile network you want to check.
Open CheckIP.ca. Your public IP address for this connection appears immediately, with its IP version (IPv4 or IPv6).
Use the copy icon beside the address, or “Copy network details” for a timestamped support summary.

Only the address used to load the page is shown. This does not tell you whether your network also supports the other IP version.

Windows and Mac: local addresses

On Windows, open Settings → Network & internet, choose the active connection, and view its properties. You can also run ipconfig in a terminal and find the active adapter. On a Mac, open System Settings → Network, select the active connection, and view its details. These addresses may differ from the public IP shown here.

See Microsoft’s network settings guide and Apple’s IP address guide for your system’s settings.

iPhone and Android

Use your browser to check the public IP. To find a local Wi-Fi address, open the connected network’s details in your phone’s Wi-Fi settings; labels vary by device and software version. Mobile data and Wi-Fi are separate connections, so switching between them can change your public IP.

From the command line

curl https://checkip.ca
curl --ipv4 https://checkip.ca
curl --ipv6 https://checkip.ca

The last two commands request a specific IP version. An IPv6 command can fail when that connection cannot reach the site over IPv6; it does not prove the device has no IPv6 configuration.

Before contacting support

Copy network details while the issue is happening and say whether you are on Wi-Fi, Ethernet, mobile data, or a VPN. The summary includes your public IP, so share it only with the intended recipient. CheckIP does not automatically send it to a support service.
