python实现自动更换ip的方法

本文实例讲述了python实现自动更换ip的方法。分享给大家供大家参考。具体实现方法如下：

    #!/usr/bin/env python
    #-*- encoding:gb2312 -*-
    # Filename: IP.py
    import sitecustomize
    import _winreg
    import ConfigParser

    for index in range(keyInfo[0]):

    try:

    # 检查是否是以太网
    if lowerRange[0] == 'ethernet':
