Python实现自动化域名批量解析分享

第Python实现自动化域名批量解析分享脚本架构：

domain_test.py：批量解析运行主程序DomainResult.txt：域名解析结果文件domains.txt：解析的域名文件

实现代码如下：

#coding:utf-8

importsocket

importsubprocess

importre

defget_host_from_file(file_path):

withopen(file_path,'r')asfr:

domains=fr.readlines()

result=[]

forurlindomains:

url=url.strip()

ips=socket.gethostbyname_ex(url)[-1]

result.append(url+'\t'+';'.join(ips)+'\t'+'ping'+'\n')

exceptExceptionase:

print(url,e)

withopen('./domain2ip.txt','w')asfw:

fw.writelines(result)

defget_host_from_url(url):

ips=socket.gethostbyname_ex(url)[-1]

returnurl+'\t'+';'.join(ips)+'\t'+'ping'+'\n'exceptExceptionase:

print(url,e)

returnurl+'\t'+'none'+'\n'

defdig_test(file_name,dns_name):

dig_command='dig'ip_result=[]

ifdns_name:

dig_command+=dns_name+''withopen(file_name)asfr:

domains=fr.readlines()

forui,full_urlinenumerate(domains):

ips=[]

full_url=full_url.strip()

result=subprocess.Popen(dig_command+full_url,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)

exceptExceptionase:

print(full_url,e)

else:

results=str(result.stdout.read()).split('\\n')

fortempinresults:

iffull_urlintempand'IN'intemp:

ip=re.match(r'.*\\t([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}).*',temp)

ifipandip.group(1)notinips:

ips.append(ip.group(1))

if'AUTHORITYSECTION'intemp:

breakifips:

temp=full_url+'\t'+';'.join(ips)+'\t'+'dig'+'\n'else:

temp=get_host_from_url(full_url)

print(ui,temp)

ip_result.append(temp)

#解析完成后，生成结果文件

withopen('domains.txt','w')asfw:

fw.writelines(ip_result)

if__name__=='__main__':

#先使用dig，失败时使用ping获取域名
