About ZeroTier One

ZeroTier emulates an Ethernet switch across the internet. Join a network with its sixteen-digit ID and your machines get addresses on it and talk directly to each other, whatever network address translation is in the way. Traffic is encrypted end to end with keys only you hold, and most of it goes peer to peer.

Because it works at the Ethernet layer rather than the IP layer, broadcast-dependent protocols and network discovery work across sites. Access control rules allow fine-grained segmentation. Free accounts cover a useful number of devices, and the controller can be self-hosted.

Strengths

  • Ethernet-level networking, so discovery and broadcast protocols work across sites
  • End-to-end encryption with keys you control
  • Traverses network address translation without port forwarding
  • Windows, macOS, Linux, BSD, Android, iOS, routers and containers

Limitations

  • An account with the hosted controller unless you run your own
  • Relayed connections are free but slow when peer-to-peer fails
  • Ethernet-level networking is more than most people need
  • Some parts of the repository are not free software
