I can do it in one word - magic!

It's basically a P2P VPN. You set up a network on the controller and then
join it from various machines. Those machines register with the network
controller, and receive an IP address from it, but the actual
communication is direct between the computers. So your data is private
and if both computers are on the same LAN, you still get full LAN speed
between them.

It use a TUN/TAP interface, for example on this laptop:

zt0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 2800
        inet 10.252.252.6  netmask 255.255.255.0  broadcast 10.252.252.255
        ether 46:96:8c:9c:02:e1  txqueuelen 500  (Ethernet)

So I can connect to 10.252.252.6 from any computer on my zerotier
network, but you cannot. You may even have the same IP address for one of
the computers on your network.

It's open source and if you want optimum security, or want to run a
network of more than 10 computers without paying a fee, you can run your
own controller.
