给改一下，使以下代码能提取到ubuntu server服务器的ipv6地址

Question

各位，麻烦给改一下，使以下代码能提取到ubuntu server服务器的ipv6地址，谢谢。（目前只能提取到ipv4）

#!/usr/bin/python3

import socket
import os
import json

from email.header import Header
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

    mail_sender = mail_user 
    mail_receivers = "*****@qq.cn"
    message = MIMEMultipart()
    message['From'] = Header(mail_sender)
    message['Subject'] = Header("ip地址")
    message.attach(MIMEText(asctime(), 'plain', 'utf-8'))
    message.attach(MIMEText(email_content, 'plain', 'utf-8'))
    print("message is {}".format(message.as_string()))
    smtpObj = smtplib.SMTP(mail_host)
        smtpObj.login(mail_user, mail_auth_code) 
    smtpObj.sendmail(mail_sender, mail_receivers, message.as_string())

def get_temp_ip(current_ip):
    temp_ip_json_path = "/var/tmp/ip.json"
    if not os.path.exists(temp_ip_json_path):
        print("No {}, dump it.".format(temp_ip_json_path))
        with open(temp_ip_json_path, 'w') as jo:
            json.dump(current_ip, jo)
            return True, current_ip

    else:

            origin_ip = json.load(jo)
        if origin_ip == current_ip:
            print("Current ip {} do not change, no need to send".format(current_ip))
            return False, current_ip
        else:
            print("The ip updated from {} to {}, update it.".format(origin_ip, current_ip))
            os.remove(temp_ip_json_path)

                json.dump(current_ip, jo)
                return True, current_ip


def get_ip():
    hostname = socket.gethostname()
    addr_infos = socket.getaddrinfo(hostname, None)
    ips = set([addr_info[-1][0] for addr_info in addr_infos])
    global_ips = [ip for ip in ips if ip.startswith("24")]
    whether_to_send, send_ip = get_temp_ip(global_ips)
    send_ip = json.dumps(send_ip)
    return whether_to_send, send_ip

if __name__ == "__main__":
    whether_to_send, global_ips = get_ip()
    if whether_to_send:
        send_an_email(global_ips)
    else:
        print("wait and no send")
