Tailscale automatically assigns IP addresses for every unique device in your network, giving each device an IP address no matter where it is located. We further improved on this with MagicDNS, which automatically registers a human-readable, easy-to-remember DNS name for each device — so you don’t need to use an IP address to access your devices. This means you can access the device monitoring, ev
