一、脚本功能
1.获取主机名
2.获取外网IP（通过多个公共API尝试） IPV4和IPV6
3.获取所有网络接口的内网IP
4.保存至文件并打印信息
输出示例：
主机名: MyComputer
内网IPv4地址:
- 192.168.1.100
- 192.168.56.1内网IPv6地址:
- 2001:0db8:85a3:0000:0000:8a2e:0370:7334外网IPv4: 203.0.113.1
外网IPv6: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
二、注意事项
1.获取外网IP需要网络连接
2.某些网络环境可能会阻止访问IP查询服务
3.如果在代理或VPN环境下，获取的外网IP可能是代理或VPN的IP
4.内网IP可能会有多个，特别是在有多个网络接口的情况下5.考虑暂时关闭防火墙
6.如果你的网络不支持 IPv6，那么相关的 IPv6 地址将显示为"无法获取"
7.某些系统可能需要管理员权限才能获取完整的网络接口信息
三、准备工作
导入库：
import socket
import requests
import json
import time
from datetime import datetime四、完整代码
