How to use the options to socket() for IPv6 multicast UDP?

I have a linux network interface that IPv6 multicast traffic is arriving on. There are both ICMPv6 packets and UDP packets arriving for the same multicast group.

How to send and receive data the same time Python UDP socket

I just learned about #python recently, I have done a small project about rasberry pi. I want to transmit and receive data between Server is Laptop, client is Ras via UDP protocol, I use Python’s socket library.

Receive foreign UDP Broadcast with Python

I have a device in the network at 192.168.123.204 which broadcasts UDP datagrams(Artnet) as 2.168.123.204 to 2.255.255.255:6454. (The network address is 192.168.123.204 but the datagram is sent with 2.168.123.204 as source.) The address 2.255.255.255 can’t be changed (no setting for that). My Python script runs on the device 192.168.123.148. I can receive the datagrams there with wireshark: but a Python
