 Unlike *zerotier-one*, *zerotier-netcon-service* does not need to be run with root privileges and will not modify the host's network configuration in any way. It can be run alongside *zerotier-one* on the same host with no ill effect, though this can be confusing since you'll have to remember the difference between "real" host interfaces (tun/tap) and network containerized endpoints. The latter are completely unknown to the kernel and will not show up in *ifconfig*.
