Matter uses IPv6 for its operational communications, and leverages on both IPv6 Unicast and Multicast addressing for accessing its Nodes and Groups, respectively

To enable the IPv6 communication with the Matter accessory device over the Thread network, the Matter controller requires the Thread Border Router. This is because the Matter controller types described on this page do not have an 802.15.4 Thread interface. The Border Router bridges the Thread network with the network interface of the controller, for example Wi-Fi.
