What is hello.ts.net?
hello.ts.net is a server administered by Tailscale staff to help new users test their network.
hello.ts.net can only be accessed over Tailscale. If hello.ts.net loads in your browser, you’re connected over Tailscale!
hello.ts.net is a private, “one-way” server. It is not accessible via the public internet, and ACLs restrict it from making any outgoing connections. Tailscale does not initiate connections from hello.ts.net to your tailnet. It serves no purpose other than to allow you to verify you’re connected to Tailscale.
How can I add hello.ts.net?
If you would like to add it for testing purposes, you can use this special invite link to accept it into your network:
login.tailscale.com/admin/invite/hello.ts.net
How can I remove it from my network?
You can remove hello.ts.net at any time from the machines page of your admin
console. Press the
icon for a link to remove it.

Once removed, it will disappear from the list, and no users on your network will be able to connect.
