Tailscale IP address
Each machine in a tailnet is assigned a unique IP address that never changes for your device, even when the machine device switches between home Ethernet, cellular hotspot, or coffee shop Wi-Fi networks. The address is assigned by the coordination server and always of the form 100.x.y.z (for example, 100.12.345.67). Use MagicDNS to automatically register memorable hostnames for machines in the network.
