Working with IPv6 sockets in Python 3.7

In this section, you will learn how we can implement IPv6 with sockets in Python 3.7.

Implementing the IPv6 server

We will start with the server implementation in a script called echo_server_ipv6.py. The first lines will be the libraries that we will use, which are socket (network and connection utilities) and subprocess (which will allow us to execute commands on the server):

import socket
 import subprocess

Then, we will create the variables: ip, port, max_connections, and server. The ip variable will have the string ::1 value, which will be the IPv6 address of the localhost server; the port through which it will accept connections will be passed as an argument to the script; and max_connections...
