    We prefer IPv4 so that we don't change behavior from previous IPv4-only
    implementations, and because some drivers (e.g., FirefoxDriver) do not
    support IPv6 connections.

    If the optional port number is provided, only IPs that listen on the given
    port are considered.

    :Args:
        - host - A hostname.
        - port - Optional port number.

    :Returns:
        A single IP address, as a string. If any IPv4 address is found, one is
        returned. Otherwise, if any IPv6 address is found, one is returned. If
        neither, then None is returned.

    This is a minimal implementation intended to cope with IPv6 literals. For
    example, _join_host_port('::1', 80) == '[::1]:80'.

    :Args:
        - host - A hostname.
        - port - An integer port.
