Python信息搜集

　　1.IP查询

　IP查询是通过当前所获取到的URL去查询对应IP地址的过程.可以应用socket库函数中的gethostbuname()获取域名所对应的IP值,代码如下:

　　查询域名www.biadu.com所对应的IP值,代码如下:

　

　  >>> import socket
 
　　>>> ip = socket.gethostbyname('www.biadu.com')
 
　　>>> print(ip)

　　

　　输出结果:

　　

   112.80.248.75

　　

　　2.whois查询

　whois是用来查询域名的ip以及所有者信息的传输协议.简单地说,whois就是一个数据库,用来查询域名是否已经别注册,以及注册域名的详细信息(如域名所有人,域名注册商等).Python中的模块Python-whois 可用于whois的查询

　　首先通过pip安装Python-whois:

pip install python-whois

　　通过Python自带的whois模块查询域名www.baidu.com的注册信息,代码如下:

　　>>> from whois inport whois
 
　　>>> data =whois('www.baidu.com')
 
　　>>> pirnt(data)

　　

　　输入结果:
