The socket server

First, we define the necessary variables for the connection, that is, the IP address for localhost in IPv6 format and the maximum number of connections from clients:

IPV6_ADDRESS = '::1'# Up to 5 clients can connectmaxConnections = 5

Next, since we have the necessary data, we create the server. It is a socket-type object that is listening in a specific port using IPv6 and TCP/IP:

# Creating the server with ipv6 support# socket.AF_INET6 to indicate that we will use Ipv6# socket.SOCK_STREAM to use TCP/IPserver_socket = socket.socket(socket.AF_INET6,socket.SOCK_STREAM)dataConection = (host,port)server_socket.bind(dataConection)

Our socket is already created. Now we must accept connections from it:

print("Waiting connections ...
