Multicast addresses are in class D, which means that multicast addresses are between 224.0.0.1 and 239.255.255.255. The ip maddress show command can be used to determine if an interface is configured to use multicast. In this example, the eth0 interface is configured to use multicast address 224.0.0.1.

~]# ip maddress show
1:  lo
    inet  224.0.0.1
    inet6 ff02::1
    inet6 ff01::1
2:  eth0
    link  33:33:00:00:00:01
    link  01:00:5e:00:00:01
    link  33:33:ff:a1:35:a1
    inet  224.0.0.1
    inet6 ff02::202
    inet6 ff02::1:ffa3:35a1
    inet6 ff02::1
    inet6 ff01::1
