 Securely connect application instances, physical devices, and virtual devices as if everything is on a single LAN. ZeroTier brings your network into user-space. No root, and no host configuration requirements.
 
-We've paired our network hyper-visor core with a TCP/UDP/IP stack [(lwIP)](https://en.wikipedia.org/wiki/LwIP) to provide your application with an exclusive and private virtual network interface. All traffic on this interface is end-to-end encrypted between each peer and we provide an easy-to-use socket interface similar to [Berkeley Sockets](https://en.wikipedia.org/wiki/Berkeley_sockets).
