A python script for batch parsing domain names into IP addresses

 

 

The script is as follows:

 

#!/usr/bin/env python
#coding:utf-8


import os,sys
from socket import gethostbyname
DOMAIN= "G:/PycharmProject/fullstack2/week1/domain.txt"

def main():
    #domain.txt stores a list of domain names that need to be parsed in batches, one per line
    with open(DOMAIN,'r') as f:
        for line in f.readlines():
            try:
                 host = gethostbyname(line.strip('\n'))
            except Exception as e:
                print e
            else:
                #result.txt stores the results of batch parsing and does not need to be created in advance
                with open('result.txt','a+') as r:
                    r.write(line.strip('\n') + ' ')
                    r.write(host + '\n')
if __name__ == '__main__':
    main()

This script is not perfect, because the IP and domain name are bound, but the IP ping fails or the machine shuts down, the following error will occur

 

[Errno 11001] getaddrinfo failed
[Errno 11001] getaddrinfo failed
[Errno 11001] getaddrinfo failed
[Errno 11001] getaddrinfo failed

 

And it is impossible to determine which domain name is not bound to the IP
