How to use Python to generate instances of local IP in bulk

The example in this article describes how Python generates a local IP address in bulk. Share to everyone for your reference. The specific analysis is as follows:

This code is used to generate a local IP address on the local computer to bind to the network card, generate a bat batch file, run this batch file, can be viewed through ipconfig

#!/usr/bin/python2.7#-*-coding:utf-8-*-# Filename:AddIPAliases.pyimport re,sys,socket,struct # 1. Determine if the IP address is legitimate; 2. Determine if the IP entered by the user is in class A,class B or Class C 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]) \.

Before you run the script, move to: Control Panel, view network--Local Area Connection, properties->ipv4, change the auto-get IP to manual 2. IP is divided into three categories: class A: Quantity 16777216, Range 10.0.0.0-10.255.255.255 class B: Quantity 1048576, Range 172.16.0.0-172.31.255.255 class C: Quantity 65536 , the range 192.168.0.0–192.168.255.255!!! So when you enter the IP, pleaseEnsure that the IP you enter is among these three categories!!! 3. If you are using an English system, change the "Local Area Connection" in the Custom Function makeips () to "regional Connection". 4. The script is a bit long because of the range () of the long integer data, wait for the prompt to be successful. 5. The directory where the script is stored will generate a bat file and a CSV file, and the bat file is used to add IP to the system, run it manually after the build succeeds, and the CSV file is used to invoke these IPs in JMeter. 6. If you want to clear the IP that is inserted in the system, move to: Control Panel, view network---local connection, properties->ipv4, change the manually acquired IP to get ip*********************************** automatically "# Converts the IP addresses of each class starting and ending to integers ipclasses=[' 10.0.0.0 ', ' 10.255.255.255 ', ' 172.16.0.0 ', ' 172.31.255.255 ', ' 192.168.0.0 ', ' 192.168.255.255 ']ipclassesint=[]for I in range (len (ipclasses)): Ipclassesint.append (Struct.unpack ('!
