What is multicast in Wireshark?
Multicast allows a single network packet to be delivered to a group of receivers. Any Ethernet, or other 802. x, address with a high-order bit set to 1 (that is, if its first octet is odd) is multicast, except for the Broadcast address (which is all ones). IP addresses in the range 224.0.
What is multicast traffic?
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication.
What is the multicast address range?
224.0.0.0 through 239.255.255.255
Host Extensions for IP Multicasting [RFC1112] specifies the extensions required of a host implementation of the Internet Protocol (IP) to support multicasting. The multicast addresses are in the range 224.0. 0.0 through 239.255. 255.255.
Where can I find multicast streams in Wireshark?
To access the Multicast streams analysis use the menu entry “Statistics->Multicast Streams”. To try out this dialog, a capture file containing MPEG2 Multicast streams can be found at SampleCaptures/video_multicast.cap.gz
Can You filter both Multicast and broadcast traffic?
That is true, but broadcast is a type of multicast traffic. So this still answers the original question. @mojjj’s answer is still beneficial because it does provide a way to explicitly exclude broadcast. – Rob Wagner Mar 9 ’17 at 19:07 | Show 2more comments 19 (eth.dst[0]&1) will filter both multicast and broadcast.
What does multicast mean in a network address?

How is multicast traffic recognized on a Mac?
Multicast traffic is recognized by the least significant bit of the most significant byte of the MAC address. If 1, multicast, if 0, not. Share Improve this answer Follow
