IPv6 in Matter

[cuongngo]

Matter devices use IPv6 for the network layer but I understand this IPv6 will be allocated by the Commissioner or allocated to the device by the Router. If issued by the Commissioner, if I disconnect the wifi router's internet connection, will Matter devices be able to communicate locally with each other?

Hello,

Maybe this video might be helpful for you: Matter Network Transport - CSA-IOT.

Matter protocol uses IPv6 addressing for its operational communication.

The architecture of Matter Network Layer is IPv6.

For further information about this, kindly refer to Matter Specification.
