Detailed example of how to use python to generate local IPs in batches

The example in this article describes the method of batch generating local IP addresses in Python. Share it with everyone for your reference. The specific analysis is as follows:

This code is used to generate a local IP address on the local computer and bind it to the network card. What is generated is a bat batch file. Run this batch file. You can view it through ipconfig

#!/usr/bin/python2.7
# -*- coding: utf-8 -*- 
# Filename: AddIPAliases.py
import re,sys,socket,struct  
# 1. 判断IP地址是否合法； 2. 判断用户输入的IP是否在Class A，Class B 或 Class C中
def CheckIP(IP,IPClassesInt):
  regexIP=re.compile('^([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])$')
  Checking=regexIP.match(IP)
  if Checking==None:
    IP=raw_input("亲！请输入合法的IP地址哈: ")
    return CheckIP(IP,IPClassesInt)
  else:
    IPInt=struct.unpack('!L',socket.inet_aton(IP))[0]
    if IPInt not in range(IPClassesInt[0],IPClassesInt[1]+1) and IPInt not in range(IPClassesInt[2],IPClassesInt[3]+1) and IPInt not in range(IPClassesInt[4],IPClassesInt[5]+1):
      IP=raw_input("亲！您输入的IP地址不在Class A，Class B或Class C中，请阅读提示信息并重新输入IP地址：")
      return CheckIP(IP,IPClassesInt)
    else: return IP
# 判断输入的数字是否合法
def CheckIPCount(IPCount):
  regexIPCount=re.compile('\d+')
  Checking=regexIPCount.match(IPCount)
  if Checking==None:
    IPCount=raw_input("亲！请输入合法的数量：")
    return CheckIPCount(IPCount)
  else: return IPCount
# 为用户生成指定数量的IP
def MakeIps(IPInt,IPCount,IPIntBool):
  targetBat=open('AddIPAliases.bat','w+')
  targetCSV=open('AddIPAliases.csv','w+')
  # 判断IP地址的数量是否在Class A，Class B或Class C的范畴中
  if int(IPCount)>(IPClassesInt[IPIntBoolTrue[1][2]]-IPInt+1):
    IPCount=raw_input("亲！您输入的IP数量超过了"+IPIntBoolTrue[0]+"的范畴，请重新输入：")
    return MakeIps(IPInt,IPCount,IPIntBool)
  else:
    for i in range(int(IPCount)):
      IPIntTrans=socket.inet_ntoa(struct.pack("!L", IPInt))
      IPInt+=1
      targetBat.write('netsh interface ip add address "本地连接" '+IPIntTrans+' '+IPIntBoolTrue[1][1]+'\n')
      targetCSV.write(IPIntTrans+'\n')
  targetBat.write('pause')
# Main 函数
print '''
**************************************************
以下信息能够帮助你更好的运行此脚本： 
1. 在运行脚本前，请移步：控制面板->查看网络->本地连接->属性->IPv4，将自动获取IP改成手动
2. IP分为三类：
  Class A：数量16777216，范围10.0.0.0 - 10.255.255.255
  Class B：数量1048576， 范围172.16.0.0 - 172.31.255.255
  Class C：数量65536，  范围192.168.0.0 – 192.168.255.255
!!!所以大家在输入IP的时候，请保证您输入的IP属于这三个分类之中!!!
3. 如果你使用的是英文系统，请将自定义函数MakeIPs()中的“本地连接”改成“Local Area Connection”。
4. 脚本由于要对长整型的数据进行range()，所以计算时间有点长，请等待成功提示。
5. 在脚本存放的目录将会生成一个bat文件和csv文件，bat文件用于向系统中添加IP，生成成功后请手动运行它，csv文件用于在Jmeter中调用这些IP。
6. 如果想清除在系统中插入的IP，请移步：控制面板->查看网络->本地连接->属性->IPv4，将手动获取IP改成自动获取IP
