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
import socket
import subprocess
import re
def get_host_from_file(file_path):
with open(file_path, 'r') as fr:
domains = fr.readlines()
result = []
for url in domains:
url = url.strip()
try:
ips = socket.gethostbyname_ex(url)[-1]
result.append(url + '\t' + ';'.join(ips) + '\t' + 'ping' + '\n')
except Exception as e:
print(url, e)
with open('./domain2ip.txt', 'w') as fw:
fw.writelines(result)
def get_host_from_url(url):
try:
ips = socket.gethostbyname_ex(url)[-1]
return url + '\t' + ';'.join(ips) + '\t' + 'ping' + '\n' except Exception as e:
print(url, e)
return url + '\t' + 'none' + '\n'
def dig_test(file_name, dns_name):
dig_command = 'dig ' ip_result = []
if dns_name:
dig_command += dns_name + ' ' with open(file_name) as fr:
domains = fr.readlines()
for ui, full_url in enumerate(domains):
ips = []
full_url = full_url.strip()
try:
result = subprocess.Popen(dig_command + full_url, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
except Exception as e:
print(full_url, e)
else:
results = str(result.stdout.read()).split('\\n')
for temp in results:
if full_url in temp and 'IN' in temp:
ip = re.match(r'.*\\t([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}).*', temp)
if ip and ip.group(1) not in ips:
ips.append(ip.group(1))
if 'AUTHORITY SECTION' in temp:
break if ips:
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
with open('domains.txt', 'w') as fw:
fw.writelines(ip_result)
if __name__ == '__main__':
# 先使用dig，失败时使用ping获取域名ip，可指定dns，如@114.114.114.114
dig_test(file_name='DomainResults.txt', dns_name='')演示结果：
