We have a big local area online, one side of each floor is a big LAN, through a large switch, then give you a line from the switch, then we own this line. That is, in fact, all the computers on one side of the building are connected in a local area! Today, the local area network of our bedroom is only in the case of one of me, I use a software "LAN Monitor" to search. It is found that there are 11 people through our small local area online Internet (see the picture below), this floor is a first grade, everyone knows that many people have not paid money, through our Gateway, free internet, no way, we changed a gateway! Oh, or those people know, I really want to kkk them. However, this method is too much. After a while, I will change it. And I will change it yesterday. I found someone to go online today! Because IP addresses in our LAN can be set. That is to say, if it is not the person in our LAN, it is almost impossible to use the IP of the same paragraph. Originally want to find a software that seal IP, but listened to them that it is very charged, so your computer is used Not yet. But I am depressed now, because I am a host, so I want to find a software that can seal IP, which big brother introduces a good software in the LAN in LAN?
My door is dial-up, I need a host, I now need a software that can seal IP in the LAN, prohibiting them from connecting to my computer, then Internet! Who can help introduce a software in the LAN to seal IP in the LAN, to be used
