    Resolve host and port into list of address info entries.

    Translate the host/port argument into a sequence of 5-tuples that contain
    all the necessary arguments for creating a socket connected to that service.
    host is a domain name, a string representation of an IPv4/v6 address or
    None. port is a string service name such as 'http', a numeric port number or
    None. By passing None as the value of host and port, you can pass NULL to
    the underlying C API.

    The family, type and proto arguments can be optionally specified in order to
    narrow the list of addresses returned. Passing zero as a value for each of
    these arguments selects the full range of results.
