What is the meaning of 'brd'?

In the output of the ip addr show command, brd stands for "broadcast." It indicates the broadcast address for the network interface.

The broadcast address is used to send data packets to all devices on a specific network segment.
For example, in the output inet 192.168.1.10/24 brd 192.168.1.255, the broadcast address 192.168.1.255 allows packets to be sent to all devices within the 192.168.1.0/24 subnet.
