Receive data using Python sockets UDP IPV6 for a specific source address and port
Comment

To receive data using Python sockets with UDP and IPv6 for a specific source address and port, you can use the socket
module. Here's an example:
pythonimport socket
# Define the target source address and port
source_address = '2001:db8::1' # Replace with the desired source IPv6 address
source_port = 12345 # Replace with the desired source port
# Create a UDP socket with IPv6
sock = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)
# Bind the socket to the source address and port
sock.bind((source_address, source_port))
# Receive data
while True:
data, addr = sock.recvfrom(1024) # Buffer size is 1024 bytes
print('Received data:', data.decode(), 'from', addr)
In this example:
- Replace
'2001:db8::1'
with the desired source IPv6 address you want to listen on. - Replace
12345
with the desired source port you want to listen on. - The socket is created using
socket.AF_INET6
to specify IPv6 andsocket.SOCK_DGRAM
for UDP. - The socket is bound to the specified source address and port using
sock.bind((source_address, source_port))
. - In the
while True
loop, the socket receives data usingsock.recvfrom(1024)
, which waits for incoming data. The received data and the address it came from are printed.
Ensure that the specified source address and port are valid and accessible. The example above will listen for incoming UDP packets from the specified source address and port. Adjust the buffer size (1024
in the example) according to your requirements.
Remember to handle exceptions, such as socket.error
, and properly close the socket when you are finished with it.
By using this example as a starting point, you can receive data from a specific source address and port using Python sockets with UDP and IPv6.
