How Tailscale Simple Interconnection Works

The most direct way to get two devices to communicate with each other is, of course, physical connection. Plug in a network cable, and you get the other device's IP, then access it without any obstacles.

But in real-world scenarios, one device might be at home, another at the office, and a phone on the road. At this point, each device sits in a completely different network environment:

1. A few devices have a dedicated, unique public IPv4 or IPv6;
2. Many more devices are hidden behind a router, assigned only a private address via Network Address Translation (NAT).

This network structure prevents devices from establishing a direct connection.
