根据脚本获取ip地址，并且打印出可用的ipv6地址，需要调用getip.py脚本，该脚本依赖python3

getip.py

#!/usr/bin/env python3
# encoding: utf-8


import ipaddress
from random import shuffle


#iprange = ipaddress.ip_network('2800:3f0:4000::/36')
iprange = ipaddress.ip_network('2607:f8b0:4005:802::1002/112', strict=False)
addresses = []
for ip in iprange.hosts():
    addresses.append(ip)


shuffle(addresses)
for ip in addresses[:20]:
    print(ip)

getip.sh

#!/bin/bash

python3 getip.py | tee t_ip.txt | xargs -n 1 ping6 -c 2
cat t_ip.txt | tr '\n' '|' > ip.txt
