socket.getaddrinfo

socket.getaddrinfo(host, port)

• Translates the host and port argument of a service into a sequence of 5 tuples
• These tuples contain arguments useful for creating a socket to that service
• The functions returns a list of tuples with the following structure:

• The family, type, and proto elements have values that would be passed to a socket object
• The canonname element is a string representing the canonical name of the host
• The sockaddr element is a tuple containing a socket address

Example of getaddrinfo

>>> import socket
>>> s = socket.getaddrinfo('example.org, 80)
[(<AddressFamily.AF_INET6: 10>,
  <SocketType.SOCK_STREAM: 1>,
  6,
  '',
  ('2606:2800:220:1:248:1893:25c8:1946', 80, 0, 0)
 ),
 (<AddressFamily.AF_INET: 2>,
  <SocketType.SOCK_STREAM: 1>,
  6,
  '',
  ('93.184.216.34', 80)
 )
]
