The Homenet Control Protocol (HNCP)

The Homenet (hnet) protocol and this documentation were last under development in late 2016. It is unknown whether the hncp package works with modern (19.07 and later) versions of OpenWrt.
The Homenet website seems to have gone off the air in 2020. A 2018 version of the site is at The Wayback Machine
This Forum article also describes the state.

The Homenet Control Protocol (HNCP) automatically manages IPv4 and IPv6 address assignment, routing, DNS, SD (ZeroConf/mDNS) and border firewalling between multiple routers in a “home network”. It is specified as a set of RFCs to implement a minimalist state synchronization protocol for Homenet routers.

hnet-full package installs hnetd to implement HNCP protocol, there is also luci-app-hnet, a luci webgui package to control it.
Note: We strongly recommend you install ipset before installing hnet-full
