Software

The open-source software acts in combination with the management service to esablish peer-to-peer or relayed VPN comunication with other clients using the Wireguard protocol. If the software fails to establish direct communication it falls back to using relays provided by the company. The IPv4 addresses given to clients are in the Carrier-grade NAT reserved space. This was chosen to avoid interference with existing networks. The configuration also allows routing of traffic to networks behind the client on some clients.[6]

Notes
  1. Although Tailscale is a service provider who sells VPN services, it is not a VPN service in the typical sense that provides censorship bypasses, but is aimed at providing mesh networking
