multicast mac maps , ip address

[sarahr202]

  Hi everybody.

I hope everybody is doing great.

I just want to verify few examples below:

ip address 199.128.1.1

The multicast mac address for the above ip address is: 0100:5e00:0101

ip address 199.140.1.1

  multicast mac:   0100:5e0c:0101

Are my examples correct ?

thanks and have a great day.

Hi Sarah,

Your conversion method is correct. But your IP address is not a Multicast IP address. Valid multicast address range is from 224.0.0.0 to 239.255.255.255
