How Tailscale assigns IP addresses
Tailscale makes it easy to connect to your network by providing you with a consistent IP address for each node (a device or a server). These addresses stay the same, no matter where nodes move to in the physical world, making them easy to manage and share with non-technical users.
By default, every device receives an IP address in the 100.x.y.z range. This IP address is auto-assigned based on the device and authorization credentials and cannot be changed by hand.
Finding your Tailscale IP address
You can find your address in two ways: via the Tailscale client, and via the command line.
For Linux-based devices, use this following command:
ip addr show tailscale0
For Windows devices, open the app menu from the system task bar and look for the IP listed in the dropdown.
- For macOS devices, open the menu bar app and look for the IP listed in the dropdown.
You can also locate your IP by running
ifconfigand searching for a
utunaddress with a listed 100.x.y.z IP address.
- For iOS devices, log in to your network and look for the IP listed at the top of the app.
