examine the multicast and broadcast packets that you captured, looking at the details of the source and destination addresses. most likely one has the broadcast ethernet address, as broadcast frames tend to be more common than multicast frames. look at a broadcast frame to see what address is used for broadcast by ethernet. expand the ethernet address fields of either broadcast or multicast frames to see which bit is set to distinguish broadcast/multicast or group traffic from unicast traffic. answer the following questions: 1. what is the broadcast ethernet address, written in standard form as wireshark displays it? 2. which bit of the ethernet address is used to determine whether it is unicast or mul-ticast/broadcast?
