Python获取IP地址的三种方法

import socket
localIP = socket.gethostbyname(socket.gethostname())#这个得到本地ip
print "local ip:%s "%localIP

ipList = socket.gethostbyname_ex(socket.gethostname())
for i in ipList:
    if i != localIP:
       print "external IP:%s"%i

return socket.inet_ntoa(fcntl.ioctl(s.fileno(), 0X8915, struct.pack(‘256s’, ethname[:15]))[20:24]) 
  
if __name__==’__main__’:

        if url == opener.geturl():
            str = opener.read()
        return re.search('d+.d+.d+.d+',str).group(0)
