批量解析域名為IP地址的python腳本

 

 

腳本如下：

 

#!/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里面存儲的是需要批量解析的域名列表，一行一個
    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里面存儲的是批量解析后的結果，不用提前創建
                with open('result.txt','a+') as r:
                    r.write(line.strip('\n') + ' ')
                    r.write(host + '\n')
if __name__ == '__main__':
    main()

這個腳本不完善，因為IP和域名綁定了，但是IP ping不通或者機器關機會出現如下錯誤

 

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

 

而且無法確定哪個域名沒有和IP綁定

 

 

完善腳本：原創

 

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


from socket import gethostbyname
DOMAIN= "G:/PycharmProject/fullstack2/week1/e.txt"

with open(DOMAIN,'r') as f:

     for line in f.readlines():
        try:
            host = gethostbyname(line.strip('\n'))  #域名反解析得到的IP
        except Exception as e:
            with open('error.txt','a+') as ERR:  #error.txt為沒有IP綁定的域名
                ERR.write(line.strip()+ '\n')
        else:
            with open('result.txt','a+') as r: #result.txt里面存儲的是批量解析后的結果
                r.write(line.strip('\n') + ' ')   #顯示有ip綁定的域名，用空格隔開
                r.write(host + '\n')
